Featureless Build

[emc002]

I'm working up what I want to do on my .308 OLL Fulton Build.
I'm trying to go featureless (Magpul PRS, MM Grip, etc.)

Is a Miclulek Compensator considered a Muzzle Brake for the purposes of a featureless build?
Does it have to be pinned if the barrel is threaded? (I think this only applied to the now defunct Federal AW Ban?)

It does not have to be pinned on a non imported semi auto rifle, unless the barrel is shorter than 16in. What does the manufactuer call it?

Edit:

That looks like a compensator to me.

That's what they're selling them as also.

So are compensators a no-no? (I know Flash Hiders are...)

Muzzlebreaks/Compensators are cool. I have a Fulton .308 too. Pm Me with any questions.

Generally compensators are considered muzzle brakes and not flash suppressors.

A threaded rifle barrel is OK and doesn't need to be covered up. Also, the pinning thing was a left over from Bill Clinton's gun ban. There's no need to pin anything to the barrel unless your barrel is less than 16" or the overall length of the rifle is less than 30" and you need to meet these minimum dimensions.

Flash Hiders are wide open at the end. This design somehow helps the unspent powder burn before it becomes a giant fireball.

Muzzle Brakes/Compensators are closed at the end with a hole just big enough for the bullet to go through. This design redirects some of the blast out the sides of the brake/comp which reduces recoil.

I was going to ask the same question regarding brakes/compensators/suppressors.

It looks like for me to configure my build as a featureless, I'll need a brake/compensator as my upper came with a suppresssor.

This is actually the reverse for M14/M1A's The opening of a FS on a M14/M1A is barely wide enough for the bullet and the muzzle brakes are wide open..

I think you are mistaken.

This is a M14/M1A Flash Hider

Note the open end.


This is a M14/M1A Muzzle Brake

Note the small hole, just big enough for the bullet to go through.

You can also see this in the Springfield Armory catalog here:

Look on page 42 to see the Springfield Brake.
Look on page 45 to see the Springfield Flash Hider.

That is not a USGI M14 flash hider. The original has a much smaller hole. The national match spec actually calls for reaming the opening larger to avoid contact with the bullet.

The "approved" Springfield M1A muzzle break has a large opening on its end.

Correct.. the pic shows a reamed out NM FS... I believe the opening on a GI FS is around .320 a reamed out GI NM FS is about .460 as a SA Inc MB is about the same .460
