Featureless and linear comps

[Angrysnarf]

Recently I was told linear comps are a no go for featureless. I was trying to get a steel kak can clone pin and welded. So linear came up like a cmmg zeroed I have lying around now.

This true?


For those wondering. 13.9in barrel with 15in handguard.

I think flash cans and linear comps are generally okay on featureless because they don?t reduce flash. I remember certain muzzle devices changing their wording so it says they don?t reduce flash, but believe there was some argument over a marketing statement holding up in court. There was one example where the device previously stated it reduced flash, then later they simply removed that statement even though the device didn?t change. I?m running a brake and cage on my featureless, supposedly that?s kosher and maybe a way to go if the flash can / linear comp idea is too gray area.

Linear comps are good to go.

Reminder that per CA laws [PC 30520(c) and 11 CCR 5460, 5471(r)], if the manufacturer of the muzzle device describes it as having "flash suppressing properties", than CA will treat it as a flash suppressor.

Basically comes down to whether or not the manufacturer of the muzzle device advertises that it reduces muzzle flash. There are some manufacturers that have stated in their ads/marketing that their muzzle devices reduce flash; which would be a no-go for featureless builds.
If you're worried about it, don't run a linear comp; just go with a straight muzzle brake or to be super-duper safe, just run a thread protector.

Linear comps are great. Just find one without the evil advertising.

I have a cmmg zeroed 556 and 9mm

But they refuse to pin and weld a kak can steel knock off

[Jimi Jah]

All my AR's have linear breaks except the AR-47.

Even the 14.5" has one welded on. I enjoy the reduced decibels.

Nice which linear comp u got pin and welded?

[Jimi Jah]

A BRT was welded to a Daniel Defense 14.5" barrel by Gunfighter Tactical. It's a multi hole forward facing linear, only 2.2 oz

I also run several others including the old Levang and KAW.

[Angrysnarf]

Nice a small kak can.

We believe you need to find one where the manufacturer doesn't market any "flash hiding" marketing, BUT ALSO, make sure there aren't a bunch of dealers mentioning "flash hiding" capabilities or YouTubers saying it is an excellent flash hider. Many people seem to think it is mainly about what the manufacturer advertises, but it is clear that actual function is a key part as well. I think a lot of those cans produce a big flash, so you probably don't have anything to worry about, but do some searching on YouTube and other dealers to see if they mention anything about flash.

I reached out to cmmg and whoewver made the muzzle brake that comes with blast redirects that screws on. Their replies are absolutely no flash hiding.

Right on.
We have been designing a brake with a screw on deflector. We will do a lot of testing before releasing it for sale so we can be confident in our answer when asked. But, we have a couple other releases before then.
