Can you name a gun that isn’t better suppressed?

M1Garand with Surefire 762K Mini

While browsing the internet, I found that people were selling threaded adapters for the M1Garand for under $20. I got this one for about $16 shipped.

For $16 dollars I couldn’t pass this up.

I screwed on a Surefire flash hider mount and placed this on the rifle for the picture above.

But, the M1Garand is probably not a good choice for suppressing. If you don’t adjust the gas system for it, you could bend the op-rod or break the receiver. An adjustable gas plug would probably be a necessity. I don’t plan to fire the Garand silenced, and I don’t trust a $16 dollar adapter that goes around the barrel to be concentric to the bore. But it is kinda fun to know that I could do it if I wanted too.

As great as silencers are, there are times they are not ideal.

An example of when it would be a poor choice due to the physics and mechanical problems would be when you are doing high volumes of fire from guns like the M249 SAW. Not only is a high volume of fire hard on the silencer, there can be other problems. Multiple sources report that the M249 barrel can get hot enough to melt the lead cores of the bullets causing them to destabilize enough to cause baffle strikes destroying silencers. Even on a semi-auto rifle, a silencer is far from ideal when you are doing very high volume rapid fire.

I recall hearing a story about some of our guys in the Vietnam war. The writer reports that he was carrying a silencer submachine gun and he observed when his group was trying to break contact with the enemy that his gun would not suppress them. Funny way to turn a phrase, but the guys with unsilenced firearms could fire in the direction of the enemy and cause them to duck and slow their movement. But if he fired a burst at them from his silenced SMG, the enemy didn’t realized they were being fired on, and continued their advancing attack.

There may be times when a silencer isn’t the best choice. Still I’d rather have a silencer and have the option to take it off than not have one at all.

222 Remington Colt AR15

Did you know Colt made a few variants of the AR15 in the .222 Remington round?

Mainly export models usually to get around odd laws about “military calibers”

There are versions in the SP1 configuration, the SPII versions with a mix of A1 and A2 parts and in rifles that are more or less “A2″s.

The above 22 rifle shipped with the Colt 3x or 4X scope.

STRIBOG SP9A1

Arfcom User N_Parker posted a great review on the STRIBOG SP9A1

So I took the plunge into the unknown and purchased a Stribog as soon as they became available. Pending a range report, I am really liking this pistol but I do have a couple of concerns. I am hoping these take-off in popularity making it an attractive platform for aftermarket manufacturers. More specifically the availability of 922r parts should the Stribog prove itself worthy as an SBR candidate.

I contacted Eagle Imports and queried the future availability of stocks and 922r parts and they replied as follows:
“No, we will not be selling stocks or any 922R compliant parts. We will only be selling the basic parts, such as the magazines and adapter”.

Disassembly: Push pins are a little tight, more about that below. Rear cap has a very nice snug fit to the receiver and needs just a light tap with a rubber mallet for removal. Buffer pads at the rear tend to bind a little in the housing so the bolt assembly will not slide out unless you pull on the buffer while pulling back on the charging handle at the same time. I assume a little lube on the perimeter of the buffer pads or at the rear of the housing will fix that.

Upon initial inspection I noticed the front side of the rear sight appeared a little rough then realized after looking at the front sight the ramp or stop had sheared off. I imagine it looked similar to the stop on the front site pictured for reference. I contacted Eagle Imports about this and unfortunately they do not have any parts available yet so they will be sending a new sight when available. Plastic sights that can break are an obvious concern but I plan on taking advantage of the top rail and will be mounting a red dot.

Front Sight

My second concern is lower push pin set-up. At first glance it appeared the rear push pin broke through the housing but what looked like a break is just basically a stepped portion of the lower housing where it meets the upper receiver. This could have been designed better. In the second picture here you can see how the pin breaks that diameter in the housing on both sides. Housing material just above the pin measures 0.082” thick which seems a little thin. Hopefully this holds up and doesn’t wallow out after time. The bright spot here is if the lower does need to be replaced it can as the upper is the serialized/registered portion.

The lower pins have two sets of grooves that engage a wire retainer that simply slips into the housing. These wire retainers apply quite a bit of tension to the pin. I was not able to push the pins out by hand or at least I couldn’t get them to budge by hand. Use of a punch and small dead blow mallet did the trick. It didn’t take much effort to break them loose; it was just a matter of quick tap to get the pin retention groove past the wire retainer. You can also see in these pics that the lower housing is symmetrical in design meaning you can move the retainers to the left side of the lower (installed in right side from factory) if you wish to push the pins out from right to left.

Rear

Front

Upper receiver assembly: Very clean machining, fit and finish. Bolt travels the length of the receiver very smoothly. The upper looks similar to the B&T GMH9 and APC9 but the noticeable difference are the screws used to assemble the B&T uppers. Grand Power uses a barrel nut to assemble the upper creating a much cleaner look.

Bolt

Buffer: Two buffer pads attach via the pins shown here.

Bolt Hold Open/Release
Somewhat of a different design, an ambi bolt hold open/release straddles the outside of the lower receiver and is held in place by the front pin.

Tension spring for BHO

Last round bolt hold open

Trigger Group
As you can see here, the trigger group appears to be a self contained unit that slips into the lower housing. I wanted to remove the trigger group for pics but I couldn’t immediately see how to remove the safety selector. I need to take a closer look at that.

Mag Release

I just purchased the brace adapter and a Gear Head Works Tailhook Mod 2 brace hoping it is compatible with their brace adapter. We’ll find out soon.
Looking forward to taking this to the range and will report out then.

Here it is in it’s current configuration. Shot 147 grain ammo suppressed with no hiccups at all.

Very easy to keep on target. Not as soft shooting as my APC9 or SIG MPX but much smoother/softer than the Scorpion and maybe a little softer than my AR 9mm SBR. I’ll need to run it side by side with my AR 9mm SBR to be sure.

Shot it side by side with my APC9.

25 yard pistol range. Left/first target dialing in the MRO. Target on right second mag. Looks like it could go up and to the right a little more but at that point I just started having fun with it.
