Not too familiar with these rifles or the law regarding flash suppressors. Thought I heard they are illegal on certain guns. Buddy loaned me his rifle. It's a brand new Springfield M1A .308. When I got home & took it out of the case, I saw it had a flash suppressor. (I'm assuming that's what it is.) Does anyone know for sure if it's legal or not?

Illegal to have a detachable mag rifle with flash suppressor. Remove it asap because you now hold an illegal assault rifle in your hands.

Flash suppressor has longtitudinal slits. Muzzle brake has holes drilled in it. That's how you can tell the difference. The CA legal version has the muzzle brake.

Good point, I should have clarified that myself.

I'm sure it's just a muzzle brake ;)

It has about 30 round holes and then 4 elongated slots, about 1/2 inch long, near the end. Would this be a muzzle brake?

That would be a muzzle break, you are fine.

FYI,
The California leagal muzzle brake and the tools (calstle nut pliers) are available from Springfield, Inc., as separate items.;)

by the way, obviously the Socialist Libtards in CA were able to detect that a change from the top pic to the bottom causes a person to be a violent criminal..... :mad:

Awesome. Thanks for the help. It's definitely a muzzle brake. But it sure seems like the brake would suppress more flash than the actual suppressor.

It only seems like that b/c you don't understand how they work. The flash suppressor has a large (relative to the bore) expansion chamber at the bore exit allowing for unburned powder to combust. The muzzle brake maintains a similar diameter to the bore to nearly the end of bullet exit and just directs gas upward while the majority of the gases and unburned powder still exit the front of the brake to leave a large flash signature.

Having said that, most muzzle brakes do reduce flash signature to a degree, but not very significantly.

OK, that makes sense. But another question, why are they illegal? Just who are they hiding the flash from? Am I looking for logic in the wrong place, the Ca. law?

They're argument for why they're illegal is that what sporting purpose does it serve? who do you need to hide the flash from if your hunting, a deer? thats just their argument, not mine obviously.

It's my understanding that flash hider was designed for the shooter. Not to hide shooter from being spotted rather not to mess up natural night vision.
If you are on the other side of barrel you can and will still see the flash, even with reduced flash.

But no flash suppressor will COMPLETELY eliminate flash signature (but, a sound suppressor will completely eliminate flash)

Wow, nice.

I thought the A2 "flash suppressor" was a flash suppressor! Doesn't seem to do very well compared to the vortex and phantom

Flash suppressors reduce the noise Decible... hence, its considered a Silencer. thats why they're banned.

some Muzzle Breaks reduce the flash signature pretty well... but they are LOUD!

That's BS. They are not considered silencers. Flash suppressors are only banned on centerfire, detatchable magazine rifles. They are banned for the same reason other "evil features" such as a pistol grips are banned: no good reason at all. See PC 12276.1 (e)

Silencers are banned (except for LE and military) on all firearms. See PC 12500-12520.

um, no.

brakes can actually increase flash and increase sound over a bare barrel. Flash supressors are quiter than brakes but not more so than a bare muzzle, if they were silencers they would be NFA items and controlled federally with a $200 tax and background checks.

A flash supressor works by keeping the gasses and unburnt powder below a certain temp and not allowing them to flash ignite when they hit the open air. Usually this is done by dispersing the gas over a wider area and allowing them to mix with the cooler air.

Muzzle brakes when forcing the gas through the small holes increase the gas pressure and thus the temp alowing the gas to more easily ignite.

Normally in the daytime you will not see the flash, you need to shoot in the dark to really see the effects of a flash supressor vs a brake.

From the muzzle end you will still see the smaller flash, it really does help the shooter keep his night vision as it can take as much as 30min to regain what is lost when you are exposed to a few seconds of light.

So how come SA doesn't put a bayo lug on the muzzle brakes? That'd be a neato aftermarket part to have, I'd think.

During the federal AWB bayonet lugs were a restricted feature. Also a bayonet dosent fit over the brake.

Haha, what a load of nonsense...where do you get this stuff? Flash suppressors don't reduce sound signature (at least not at any perceptible level, though muzzle brakes make the rifle louder to bystanders b/c the concussion is directed back and to the side [and up]), they are not considered "silencers". Seriously...where do you come up with this stuff?

Actually I've seen flash suppressors for the M16 that have a serrated edge on the end that makes the suppressor look like an apple corer, and functions much the same way. Supposedly was designed for riot control, but seems like it'd make a descent substitute for a bayonette.
