flash hider position

[corey4]

i am going to be putting together a 12.5" upper for my SBR, but the problem i have is that the flash hider sits just inside the hand guard.

my question is will it be ok for a small part of the gas port/vent to sit just inside the hand guard? i would assume getting your hand close would be uncomfortable. or should the whole FH be outside of the hand guard, and by how much? i know on my DD MK18 the ass of the FH comes right to the end of the HG.

as seen in the pics, just a cunt hair of the port/vent will be inside the HG. if i thread the FH out to a few threads engaged, then only the rear portion of the FH will be tucked inside the HG.

the last pic is showing the muzzle right at the end og the HG.

i want to go with a triarc barrel, but if i have to, i'll have my 16" barrel that is currently on the upper cut to be just outside of the HG.

The Bravo Company extended A2 flash suppressor might be just what the OP needs.

I would be hesitant to have that venting that close to the end of the hand guard. I'd get a different flash hider.

Would one of these work, they are 1.2 diameter, 3.5 long. Problem is they aren't flash hiders, rather flash directors - they kind of throw it forward.

If that's too long, this one is the same diameter but only 1.75 long: https://www.kakindustry.com/kak-indu...slim-flash-can.

Flash similar to an A2

That would be better looking IMO. Didn't think about the various linear comps that are out there.

There used to be pictures but it looks like those are gone now...

I don't think I would go with a linear comp. From the videos and reviews I've been looking at, they seem like flame throwers. I thought about The extended flash hiders, but they won't work because the extended portion is the cage portion, not the the thread portion.

This should probably work. I didn't even think of this until you guys posted about the linear comps.

The Covert Comp provides a unique combination of low blast, recoil compensation and low light performance not found in other muzzle devices.
The unique design directs blast downrange and away from the operator.
It moderates felt recoil, allowing for faster follow ups.
It provides low light performance nearly as good as the common A2 style muzzle device.

People keep saying that, but I’m not convinced its true. I like BRT alot, but that device was one of the flashiest devices tested here: https://www.thetruthaboutguns.com/ar...ider-shootout/ , which included some straight up muzzle brakes and comps.
I’m sure its great at the whole being a linear comp thing, which is obviously its main purpose. Its also a well made part, with perhaps the best in class form factor. But its not as good at reducing flash as an A2.


OP, there’s no way around this. If you don’t want to use a linear comp, you need a longer barrel or shorter handguard. Maybe a spacer from ADCO might be enough. Thread adapter/extenders exist, also. I recommend barrels an inch or more longer than the handguard is, nominally. The shortest I’ve had work out right was 3/4” longer barrel than handguard, nominally. And it has a linear comp taper mount.

Sorry I cannot give anything other than other people’s reviews. I have a covert como, but have yet to try it. The build I bought it for has been on the back burner.

The only thing I could criticize on the Review you cited is that they only used one type of ammo. Using couple different ammunition types would have made it more interesting, and they weren’t exactly using top tier ammunition for the test.

You may be right about either changing barrel or hand guard.
