PDN: Concrete Bullet Ricochet Video

by

Rob Pincus made this great little video showing rounds being deflected when hitting a hard surface.

Broken AR15 gas ring.

by

A while back I picked up a used old Colt AR15 upper.  After I received it, when I first cleaned it I considered replacing the gas rings and extractor spring due to the clear fact that this upper had been used a good deal.  I talked to Shawn about this, and he suggested since it wasn’t going to be my go to gun, leaving it and seeing what happens.

Well a broken gas ring happened.  The upper functioned fine, and I have no idea where the broken section of gas ring went, but when I went to clean the upper yesterday I found one of the rings had failed.  So all the gas rings got replaced and a new extractor spring was dropped in.

So while this parts failure didn’t stop the gun from running, it is a good example of why we need to do preventive maintenance on anything our lives depend on.

German Infantry Squad Tactics in WWII

by

The machine gun has been a major force multiplier in infantry combat.  Unfortunately many unit leaders do not know how to employ assets like Snipers, Machine Guns, and Indirect fire effectively.

The rise of portable belt fed machine guns pretty much eliminated the tactic of the mass human wave attack.  This also allowed for smaller elements to suppress the enemy with fire so other elements could flank.

It drives me nuts when I hear people say that machine guns have no practical use.  Besides being fun they are also a cornerstone of modern infantry tactics.

Vega Force Company– The GBBR MP7 by Ivan Lam

by

We have a guest review from Ivan Lam, from Hong Kong for something new today. We have  many readers from Asian countries among other, who can not own real firearms. We appreciate all of our readers, so we are going to post reviews of some of the airsoft guns that those who can not have the real thing, can still have something to read and enjoy and may help them decide on products they can find and use. Airsoft is certainly popular all over the world so we will try to  have some more future reviews on airsoft.  ( ST )

Vega Force Company– The GBBR MP7

May be you’re airsofter who want to get a little bit more “realistic” feel , or may be you’re someone who lives somewhere with tight restriction on firearms. The GBBR (gas blow back rifle) is a good choice to play with. Shooting at paper, steel targets, cans, or even your friends (with eye protection) are good options when playing with this beauty.

So, why MP7 and why VFC?

 

10492562_801979023176272_1303075110540141095_n

 

I threw that cardboard box right after i got my MP7. Lack of foam or any kind of soft pad to protect the gun. What I’ve got was a Magazine inside a plastic bag, the gun in a plastic bag (heavy duty though), and the manual. No BBs for test or cleaning rod included.
I think it’s okay to have this kind of packing, however some foam may be better.

Magazine
The magazine is heavy (for airsoft) , weight 550g. Holds 44 rounds, slightly more than the real long magazine. Airsoft players who use GBBR are more to the “realistic” side of the airsoft spectrum. So no more hi-capacity bull shit like 300 rounds in a AR magazine, no more spray and pray. Using Top gas (green gas) with around 80 degrees, the magazine is able to shoot 80 rounds plus.

 

10403110_801978743176300_8619995802702483841_n

 

My magazine is the first version of the VFC (left one). And I just brought a 2nd version Magazine (right one) , with modifications to secure the mag better. In addition, the new version provides an addition of 0.1J power.

Recoil
I may say it’s fantastic in this size. It’s weird while the firearms industry try their best to reduce the recoil, the airsoft players just do whatever they can to increase it. Sure it’s no way to compare with the WE M14, with a much bigger bolt carrier. The video below may give you an idea how much recoil this little thing got (I think I”ve shoulder and griped this properly) :

http://youtu.be/QUHwMSZbraM

I may say this is realistic. Insert the magazine, charge it, pull the trigger, and bolt lock to the rear after the last shot. Bolt release is functional.

Full-auto is always a concern for GBBR players. You may not need this, but if your GBBR can dump one mag smoothly with one trigger pull, that means your GBBR is smooth and good enough for use. Again, with green gas and around 80 degrees, I’ve no problem empty the Mag without diminishing performance (in terms of rate of fire).

10494657_801979049842936_8406354050190659004_n

 

One of the feature is, the VFC one is the only 1:1 scaled airsoft gun on the market.
And they got license from H&K, so VFC may put any kind of marking on the MP7. Probably half of the price is paid for the markings.
Compare to his competitors, Marui / KWA/ WE have a smaller scale that the real one.

Disassemble
Disassemble can be one of the fun part of using GBBR. It’s really easy to field strip the VFC MP7. Just 2 pins and the stock, bolt carrier, and recoil spring is out.

 

10401603_801989649841876_3648642016523558212_n
power

Unlike AEG (airsoft electric gun), the power varies with the weight of the BBs. (Tons of technical shit need to explain though)
With a hot weather in my place,  around 80 degrees, this gun shoots
1.3 Joule with 0.2g BB (~375 fps)
1.5 Joule with 0.25g BB (~375 fps)
1.7 Joule with 0.3g BB (~350 fps)

Just bear in mind, GBB (gas blow back) system, or anykind of system relies on green gas/propane can be affected by the temperature a lot.
And finally A+ studio announced they’re producing  N.P.A.S. (Negative pressure adjustment system) for VFC MP7 to adjust the power.

10478559_801978769842964_5036284868455043918_n

 

In-field
The stock sucks as always. It’s firm, and having 3 position for adjustment is good. But it’s really a pain in the ass putting this against the clavicle. Wearing a PC/ chest rig may help, but no after-market rubber pad for MP7 available though.

The length of the barrel is really good for CQB situations. I tested My MP7 out last weekend, and felt fantastic using this running around.
some high lights in this video:

Modification
Got my bolt and recoil spring guide polished as below. Unlike real firearms, compressed gas (propane/green gas) are relatively weak, and everything got to be smooth. Polishing these make the MP7 have better recoil and smoother action.

 

1560554_801989676508540_80051972990777433_n

REMINDER: don’t polish too much, just remove the black paint on it is ok. I used 400, than 1200 sandpaper for the work.

Also, some mod on the rocket valve, which reduced the power to a CQB field level.

Cons
Recoil spring guide is not smooth enough, created some weird sping sound when I pull the bolt back slowly. So I polished it. Some people broke their muzzle thread, simply because there’s a inner body in this gun. However it’s completely made of plastic. (as shown below) This make the gun itselfs lighter, which is good for better recoil. However it’s just not strong enough, I’m still wondering if I’ll put a suppressor on it. Seems there’re still no aftrer market product for the inner plastic body.

 

10378246_801985689842272_1721934990647053665_n

 

The VFC MP7 impressed my a lot. If they can fix that plastic inner body problem, things will be even better.

Childrens School Book Bag Protection from Gunfire

by

It is a dangerous world out there, and as uncomfortable as it is to think about, the current state of the country means not every one is armed to step up to defend the most helpless among us.  With that in mind and the recent  atrocities, we decided to do some testing on something often suggested as a means for children to protect themselves in case the unthinkable happens and no one is around with a gun that could otherwise stop the threat.

IMG_3695

IMG_3697

You may have heard or read about the idea of kids using a book bag as a means to trying to stop a round from an active shooter. I have even read some talking about bags lined with soft armor.  After my tests last year of seeing what common rounds would do inside a house, and the difficulty or even rifle rounds penetrating books and some tests shown on Best Defense years ago by Rob Pincus, I can attest to the ability of books to stop about any rifle round.

For the test, we filled a pack with some real text books. from a relatives left over college semester. and some magazines to simulate a note book of just paper.  Nothing else was added, not soft armor, or plates sewn in to give it any more help to stop a round. This was meant to see how it would do if books and some nylon was all you had.

Rounds used were 5.56 in M193 and M855, 9mm using NATO ball and .45ACP ball as well as 12 gauge 00 buck, slugs and the ever popular ( though absurd) birdshot.  Five rounds of each got fired into the bag to see how it would penetrate.  We could not set the Q target against the bag without knocking it down or tearing it every shot, so we settled on setting it a few inches away.  The test was not meant to show any blunt trauma, just penetration. Again, for those who will complain.. this was not scientific, nor does it prove anything as a hard fact, thought we feel it is useful and gives plenty to think about.

IMG_3704

First up. was 9mm ball, NATO pressure ammo, Fired from about twenty feet, as if the victim was running away. We later found even contact shots had the same result.  the 9mm failed to penetrate beyond a few inches of book and barely moves the bag.

IMG_3706

One manages about  3 inches, but most stopped inside the book. We fired another five rounds of 9mm to the same result. Those that did not stop in the books deflected at harmless angles. We both expected better performance since the hotter 9mm load is often touted as being a decent round for penetration.

IMG_3717

Next up was the .45ACP 230 grain ball ammo. Shot from the same distance

IMG_3719

Same results from the 45 with just a little deeper penetration into the books but with more damage to the books by this point. The bag did flop and move more violently, and for a second we thought one may have gotten through, but, once again, nothing got anywhere close.

IMG_3722

Above you can see the results of the .45ACP ball rounds on the books. Several 45 ball rounds were found in the books with almost no deformation.

Next up was the 5.56 fired from standard 16 inch Colt 6920 with 1/7 twist barrel from the same distance as the pistols.

IMG_3728 IMG_3723

To my absolute not surprise at all. Nothing got even close. Equally ineffective was the M855 round.  Both rounds fragmented inside the books and nothing big enough to even speak or was recovered once we started to sift through the remains of the bag and books.

IMG_3738 IMG_3740

Next we fired the 12 Gauge with the 00 Buck. Looking at the pictures with no back ground it may look impressive, but the pictures out of context tell a lie.  The dead center hit was from one of the pellets going high and missing the books in the bag. Sure this would happen in real life, but the point was to see what would make it through books being used as protection. Obviously a head shot would render it all a wasted effort, but that is not the point of this test. The other “hits” resulted from deflection. The buck hit the books, flattened and deformed and went around and out the sides. There was no real penetration. I am not really sure how to label this in contest of the test since none of the made it though the protective layer of books proper, but hits did get on paper.  Something to think about, and it may be a fluke because of the harder book covers and thickness, Obviously there is not real way to predict anything a round will do after it hits anything other than air.

IMG_3748

Next up was the punishing police slugs from the 12 gauge. five rounds from the same distance as the rifle and pistol. Nothing at all on paper. The bag sure looked like it felt it though. Damage to the body even from the slugs not making a hit  would be significant in my unlearned medical opinion. But I suppose it still beats getting a 12 gauge slug through the back.

IMG_3755

Lastly was every moron’s favorite home defense shot gun round. Birdshot. Nothing even got mush past the nylon bag, but as soon as the shot hit the hard cover book, they all deflected. lost most of its energy and followed the inside of the bag around an came out the other side, I guess you could call it a “hit”, though the pellets did not even go all the way through the cardboard, and did not even do much to the books. The shot did scatter everywhere once hitting the harder books and then deflecting.  Since it did not penetrate even the soft cardboard, I have no idea what it would look like on a human. My guess is the skin would be broken and some bleeding and pain, but not enough to kill a grown person, though it would still be terrible on a kid.  Of course the further away the person got from the shooter, the even more useless the bird shot would become. Another 20 feet and maybe safety glasses would be all you needed after a shot to the books and bag, but still its something to consider.

IMG_3756 IMG_3759 IMG_3763

After testing the pistols and rifle rounds again at contact distance and seeing the same results, I took the books apart and we sifted through the remains out of being curious. The closer fired 45 rounds seem to deformed a bit but not much, no fragmentation to be sure. Even less from most of the 9mm, I believe most of the damage to both was from fired rounds hitting already embedded buck shot or other bullets.  The lead buck and slugs became blobs of every shape and size  with the 00 buck flattening out but still looking in some what original condition while the slugs looked to have suffered great damage.

 

Could you use a bag full or books for a last ditch protection? Absolutely. If you had nothing else and got caught in the open, you sure could do worse,  Children should be taught to try to use the bags for cover, maybe even being coached to snatch a loose one up and wear one on the front and back while trying to make an escape if possible if it was not so heavy it impeded speed.. Stack books behind a door or desk being used to hide, turning it into cover would also be a great idea. The ideas are many and I will leaver that to the people more qualified than I am to advice you on your kids protection.  But, just like strategically placed books and shelves in the home to protect you from gun fire, the books in a pack will do the same if it came to that.

Eyes, Hands, and Handguns.

by

Article submitted by Mark Hatfield.

Eyes, Hands, and Handguns.

This could be about shooters with poor uncorrected eyesight, it’s not.  It could be about shooters who are cross-eye dominant, it’s not, though it will touch on both of those concerns.  If you shoot only for sport, competition, hunting, or fun, then you don’t need to read this either.  But if you train for serious social purposes…

Fifty years or so ago a fellow named John created a cut in my right eyebrow.  He used three rapid jabs with the sharp edged ring on his hand, a Boy Scout ring no less.  Being not much of a fighter then, and hopefully somewhat better now, the fight ended then.  He may have actually been trying to destroy my eye but that didn’t occur to me at the time.  Anyway, later back at my home, standing at the bathroom sink looking at myself in the mirror, one half of my face was completely covered with blood.  I started cleaning from the bottom up, I kept looking for the wound, a grievous one of course it had to be.  I was surprised when I found it in the eyebrow.

Cuts to the face may bleed a lot, some ‘knife fighters’ even advocate a slash to the forehead to create bleeding to blind the opponent.  While the wisdom or not of this move is not discussed here it is true that our eyesight is easily affected.  My eyesight has many times been affected by my own sweat or chemicals in the air which made me tear, often burning tears.  Smoke from smoke grenades sometimes was worse than tear gas.  Common household cleaners used in a small room can be affect the eyes as well as the lungs.  In years past, for reasons I never discovered, some heating systems could cause me to have serious tearing and burning of the eyes.

Never forget, there is also the old trick of throwing sand, bleach, lye, and other nasty things into eyes.  Even soda or lemonade be a problem.  Remember, the person who answers the door or approaches you ‘innocently’ holding a coffee cup or soft drink cup may not be so innocent as they appear.  Think of how much even an eyelash on your eye is so disturbing.

While constantly wearing some form of eyeglasses, prescription or protective, does help a lot, that is not the point, the point here is…can you shoot with the other eye?

Most people who train shooting for defensive purposes, hopefully, will train to be able to use either hand.  While one might prefer to shoot using both hands at the same time, the serious shooter needs to be able to use only one, either one, and should work seriously at this.  BUT (And a big BUT this is) though you may practice to be able to use either hand, can you use either eye?

The hands and arms are very likely to be injured if you take incoming fire, after all, they are out there in front of your face and body but the eyes are also easily disturbed.  You may train to be able to shoot with either hand equally or near equally well but do you always use the same eye?  Aligning the gun to the eye and even just to the face can be very different than what you are so accustom to.   You may get a big shock the first time you try it.  Your performance will not be the same, you may find it difficult to align the gun with the target for ‘non-sighted’ fire let alone trying to align the sights.  This might be an ‘eye opener’ that your skills are really less than you thought.

Try these drills, some slow fire and some acquiring the target and getting off a shot quickly.

Right hand, right eye.

Right hand, left eye.

Left hand, right eye.

Left hand, left eye.

Most shooters will quickly notice that the drills where the hand and eye do not ‘match’ are the most difficult.  The good news is that improvement comes quickly.  While such drills need not be done at every practice session, they should be done more than just ‘once in a while’.

For those of us who always wear prescription eyeglasses or contacts, sometimes TAKE THEM OFF, put on clear protective glasses and shoot with no correction for bad eyesight.  Even sometimes do it in connection with the ‘hand/eye’ drills.  (If you are at a public range or other people are shooting, face AWAY from other shooters and not down range while changing glasses)

At close contact, when being hit or grabbed, often one of the first things which happens is that the wearer of eyeglasses loses them,  Can you shoot without yours?  I should ask instead  ‘Can you hit without yours?

Even doing a little bit of these drills can can cause significant improvement, even more important is learning exactly what your limitations are.  Don’t wait for a gun fight to find out.  Consider if you have to explain to a judge and jury why you shot at someone when you couldn’t see very well.  It’s better to not just have the skills, but to be able to accurately explain that you knew just what you could and could not do.

Battle of the Concealed Carry Compacts, Smith & Wesson is Winning

by

Glock and Smith & Wesson have been going toe to toe for several years in the Law Enforcement market. While Glock has slowly been screwing up their reputation, by fielding new pistols with Metal Injection Molding (MIM) parts, reliability issues from those parts and single stack 380’s that no one has asked for, Smith & Wesson has introduced an M&P line that has been eroding Glocks estimated 65% LE market and a single stack 9mm with the Shield. Now Smith & Wesson is capitalizing on Glock’s failure to answer the Shield in 2014, with a single stack 9mm of its own, and is getting a leg up on a future Glock single stack 9mm. Smith & Wesson has listened to the complaints about the Shield, which was mainly the external/manual safety, and has now released information that the Shield will be available without an external safety.

S&W Shield no Safety

S&W Shield no Safety

I am a hardcore Glock fan as most of our readers know. If you have read my articles on Glock, you know my disappointment in the G42, its caliber choice and the issues with MIM parts since 2009. Glock’s failure to maintain its reliability by saving cents on the dollar to go to MIM parts, and its failure to recognize the single stack 9mm market, is really hurting them in my opinion. Smith & Wesson is slowly chipping away at Glock’s  hold on the LE and Civilian market. With Smith & Wesson’s announcement on the new Shield, it is continuing to chip away at Glock’s future ambitions in the single stack 9mm market.

Shield No Safety Option

Shield No Safety Option

The main reason I never really liked the Shield was the external/manual safety. There is nothing wrong with an manual safety but I like to keep all my defensive firearms as close as possible in operation.  I think this is where others, who were used to carrying Glocks and M&Ps without the safety, wanted the Shield to mirror the same feature. The Smith & Wesson Shield is relatively inexpensive and have a few years of reliability on them. It looks like Smith & Wesson is winning in the single stack concealed carry 9mm world, now and in the near future.

With the recent announcement of the H&K VP9 Striker fired pistol, Glock might want to rethink what it has been doing over the past five years.

Heckler & Koch VP9

Heckler & Koch VP9 Striker Fired Pistol

Final Thoughts:

I have only been buying pre 2009 Glock’s for defensive carry and home defense as they do not have MIM parts. Hopefully Glock will re-evaluate the steps it has made in the last five years. For now it looks like the Smith & Wesson Shield is continuing to solidify its place as king of the single stack 9mm’s. Even if Glock comes out with a single stack 9mm next Shot Show, there will still be the MIM part issues and as we have seen with the G42, possibly reliability and part upgrade issues.

First Focal Plane vs. Second Focal Plane

by

Often I have had to explain to people the difference between the first and second focal plane scopes.  Now Primal Rights has a nice article explaining the difference between the two.  The article can be found here.

Personally I prefer first focal plane as my reticle and my target will always stay the same proportions to each other.  One thing to note is that newer FFP scopes have much better designed reticles then older scopes.  Many of the old FFP scopes used reticles designed for SFP scopes, so the reticle would end up being very thin or very thick on one or both extremes of magnification.  Most newer FFP scopes have well thought out reticles that remain useful thoughout their entire power range.

But in the end, the important thing is to know your scope.
