The Kalifornia Legal M1As have a muzzle brake, not a flash hider:


Muzzle brake is OK, Flash hider makes it an "assault weapon" in California.

For anybody needing to make their M1A California Legal:

I'm told the the Flash Suppressor Removal Tool from Springfield is highly recommended:

Tool :


Don't use vise grips :)

I know the difference but the ones I have seen in my local gun shop have had flash suppressors on them, what im asking is could they look the same but have different dimensions that make them a muzzle break and not a flash suppressor?

they do not have a bayonet lug on them.

Could it be the store just doesn't know the law?

its a possibility, I would think / hope that the FFL dealers would know state laws.

I have however seen them at two different gun shops in two different counties, they are run by the same person I assume this because they have the same name?

There used to be some guy who welded a washer or something on the end of a normal FH turning it into a MB. I think that some of the ports were closed, too.

Maybe that's what you are seeing.

Got any decent pics?

Where do these come from?

Yes, where do these come from? I'm interested too!

I remember that some of the Norinco/Polytechs had them during the AW ban days, but since the ban expired in 2004, the only market for such silly items is in CA......

I've got the Springfield, Inc. "brake" on both of my M14 type rifles. They don't really function as brakes (if you want a true brake, get the Smith brake, it really works), but serve as a substitute for the issue flash suppressor in CA. The interior on the Springfield brake is the same reamed-out dimension as a NM-conditioned flash suppressor. It just has holes instead of slots. I haven't noticed any braking effect nor any increase in muzzle blast with the SAI thingies.

Here's another source. Just scroll down half way:

Flash suppressor:
A couple of months ago a friend of mine was at the Bakersfield gun show & was trying to sell his Polytech m14 Sporter (he'd had it about 10 years). The original muzzle attachment (as supplied by Polytech) looked like the above flash suppressor but had no holes or slots. There were indentations that looked like slots. Well, before he bought the rifle from a gunshop, someone had milled out the indentations so they were slots like the suppressor above. So, he thought it was sujpposed to be that way.

Myself and other friends met him at the show & walked around a while. He didn't sell it. I noticed the suppressor but it didn't click with me that it made the rifle an "assault weapon". We were going to meet for lunch so everybody got in their own vehicles & left the area. We waited quite a while at the restaurant for him. When he finally showed up he said the DOJ approached him in the parking lot at the gun show & confiscated his rifle, saying it was an "assault weapon".

The DOJ agents didn't arrest him. They told him a report would be filed with the local DA & it was up to the DA if they wanted to persecute (or is that prosecute?) him. About a month later a Deputy DA called him & told him he wouldn't be charged with any crime. However, they would be keeping the rifle.

So, lesson here is:

DON'T PUT A FLASH SUPPRESSOR ON YOUR M1A/M14 (and probably a few other rifles that have detachable mags but don't have pistol grips, like an M1 carbine, Remington 742 (or is it 740???), whatever).
