20/20/20/ 1,000

Back  in 2005 I believe it was, I  was at work reading an issue of Guns &Ammo  instead of working.  That month Jeff Cooper was giving his thoughts about the war in Iraq and  dumping on the AR15 and 5.56mm  as he was wont to do. This never did sit well with me. Fast forward to a few months later and Again I was reading Cooper’s column and in it he talked about the  “20/20/20 1K challenge he thought up.  That is, 20 rounds on a 20 inch target and 20 seconds at 1,000 yards.  He opined that  it most likely be done with a 762MM semi auto like the match M14.  That generated a chortle out of me  and got me thinking.    Could it be done?  I wanted to know.  Unlike Cooper I thought using an M14  for the attempt was a dead end as the recoil and movement of the gun  would make it  nigh impossible to keep on target firing that fast.  Not to mention the  gun is a nightmare in my opinion.

In 2006 I started my attempt at making this challenge.  I tried it many times and approached it a lot of different ways.  I never could quite hit the time limit or keep all rounds  on target.  I worked up to it in practice.  I did 500 yards in 20 seconds on a 20 inch target, and got that down pretty good, then I moved up to 700  and so on in increments.  I tried using  heavier and heavier and longer barrels on precision ARs for the extra weight.  I put lead in A2 buttstocks to add more weight and I even considered tying sandbags to the fore arm FF tube.    I stopped short there as it felt like was getting too far from accomplishing the challenge with something a rifleman could and would carry.

The closest I came was 20 rounds on the target but in 21.6 seconds.  Close. But may as well have been  an hour too long.   This went on and on few times a year since 2006.  Then yesterday I did it.

I had no intention or expectation that I was even going to try it again today.  After discussing it with Howard last night, I realized that is why I managed to pull it off.  I was relaxed, I was not putting pressure on myself,I was just having fun after doing some other testing.     My purpose for being at the range was to test the federal gold medal  556mm ammo using the Berger 73 grain VLD  at 500 yards and do the follow up  part 2 of my Colt Accurized Rifle review.   While shooting at a steel gong at 1,000 yards it was  noted how calm conditions were and how dry and hot it was with temps in the high 90s.       I zeroed in on the gong and placed the cardboard target to the left of the steel.    With the idea in mind to get everything right on the steel, note  my data , then shift to the Q target and start the attempts.

With a spotter ready to  shout any misses to me as I was firing, I loaded  thirty round mags with my handloads of the sierra tipped match king 77 grain  bullets and 24.0 grains of Varget.  My idea is I would of course miss a few but If I could shoot more than 20  rounds, I could have extra rounds for the misses and still get  20 on target.

The gun is the Colt CR6724 HBAR Elite.   This is a 24 inch heavy match barrel with freefloat tube.  The gun also has a magpul PRS stock, and Atlas Bipod.  The optic is the Nightforce NXS 5.5x-22x with 56mm objective lens.  For the day’s testing I had took out the colt match trigger and had installed a SSA trigger  and it is a good thing I did.  To help even more I put a sand bag between the bipod and mag well.  This let me push the gun into something to get some weight behind it.

After  two  tries I was getting close  to pulling it off.    I had already made up my mind that I wasn’t going to pull it off.  So I decided to just see how close I could come.  On the last try I was down to only 25 rounds left after  5 rounds used for sighters because of a  small wind change.

After firing  them   all up it was time to drive down and take a look.   When we  counted them up I couldn’t believe it.    I kept  looking to make sure some holes were not just  holes made by rocks that flew up from near misses.   But I did it, I finally  hit the goal I have been after since 06 when I first seriously started to attempted it.

Below is me with recovered target trying to hide the stupid grin and dumbstruck  face.

After all these years I  finally did it. And its a good thing, at almost 42, I did not have many years left of eyesight that could still be corrected. My only regret is that my friend who is my usual partner in crime for these  pie in the sky attempts wasn’t there to share in the moment with me.   He has always been there to help me with the 1,000 yard iron sight  with AR15A2 hits and the K-31 at 1233 yards and our 1-mile shot.   It just wasn’t the same with him not there to share in the moment with us.

Howard asked me if now that I had done it, could I do it again.  No. I do not think I could pull it off again. I believe the only reason it worked this time as because I was relaxed and not taking it as serious as normal. I had  put no pressure on myself.  Another factor was once again the weather conditions allowed  success that time. The high temp, thin air and almost no wind and what little there was blew in from my 6 oclock.

It’s still strange to think that I have pulled this off after so many years.  It’s that same feeling you had as a kid the day after Christmas. Nothing to look forward to  for a long time almost.

25 rounds fired. 19.8 seconds.  20 inch by 18 inch target, 21 hits, 1,000 yards.  7-10-2018

Optic of the week: Matech BUIS

The Matech sights that come from Colt have the Picatinny marking.  I have not seen this marking on these sights from other sources.

Some time back, I’m not sure when, the U.S. Military adopted the Matech Back Up Iron Sight (BUIS) as the new rear sight for the M16A4 Modular Weapon System and the M4/M4A1 MWS. That could lead one to believe that this was the best, most durable, combat ready rear sight around. Boy would you be wrong if you thought that.

Outside the military, many people have different desires for what they want out of the BUIS. Some people want a sight that locks in place and is as solid as a bank vault, those people tend to like the Troy sights. Other people want cheap, so they go with the Magpul BUS. There are a few sights that are adjustable for range with a micrometer type adjustment such as the KAC 2-600m BUIS.  There are a wide variety of features available out there, and the Matech has a pretty unique combination of them.

The main draw to the Matech is that is had a lever on the side for changing the distance setting.  This lets you quickly set the sight for settings between 200 to 600 meters, but you can not make fine adjustment for range.

An annoyance of mine is when I can not find detailed information about a product.  I know this sight was designed for use with M855 on both the M16A4 and the M4/M4A1 Carbines but I have not been able to find out what the calibration on the adjustment is.  It might have been set for the 14.5 inch barrel, or a 16 inch barrel, or the 20 inch rifle.  It might be a blended adjustment meant to be close enough for the rifle and carbine.  We just don’t know.  But in any event, it should at least keep you on a Echo Target (40″x20″) out to 600 meters.

There is a line (with out a notch to lock it in position) between the 300 and 400m marks for zeroing a M16A4 at 25m.  When zeroing a M4 at 25m leave the sight on the 300m mark.

The sight locks down, but it does not lock in the up position.  This was chosen as to allow it to move should the rifle be dropped.  Sights that lock open can be more likely to break when locked up.  Unfortunately these sights tend to wear out and stop locking in the down position.  Countless discussion and youtube videos can be found about this.

For example:

Downsides to the Matech BUIS are:

  •  It is huge, much larger than most other BUIS.
  •  If you over tighten the clamping screw and bar it will break!  Snug it up and tighten 1/4 turn past that, no more than that.
  •  You are suppose to replace the screw that is used to hold it on if it is removed from the weapon.  Most of us won’t have multiple screws laying around.
  •  It wears out!  The rear aperture latch wears out and will not stay latched down.

Now I wouldn’t say it is a terrible sight, but I do not recommend buying one.  If you already have one I wouldn’t bother to replace it unless it breaks or wears out.  Just make sure you check the distance setting on it before you shoot.
