308 michulek on 5.56 barrel

[stephenn82]

I did some searching, no dice on here. I know that Cali law states that a compensator for a rifle must have the opening at end be the same as bullet diameter. Jerry Michulek doesn't make compensator with a 5.56 opening that is threaded for 5/8-24. He does have one for .308 in that model, or a 5.56 is 1/2-28. I seen on the internet every where that "this barrel swells" and could cause misalignment with the comp.

So, legally, could one use a .308 comp on a 5.56 barrel? my intuition tells me no. But i would ask you all who have lived adn built in this state for quite some time before i just do.

Its hard to find a great 5.56 melonite barrel that doesnt have 5/8-24. Unless you know a prefect setup for about 210 or less that has 1/2 threads, and wont cause issues.

What part of California law, please?

confused.

223/556 barrels have 1/2x28 threads
308 has 5/8x24 threads

what your saying is the opposite.

NOTICE*** THIS BARREL HAS 5/8-24 threads to keep the bore at the muzzle from swelling like most barrels threaded 1/2-28. The tighter bore at the crown gives better accuracy.

As to the OP's question:
I think you are confusing the Featureless Rifle guide's advice about CA law "flash hider" designation where a wide-open muzzle device (much wider than bullet diameter) should be avoided to keep on the straight-and-narrow.

A .308 compensator's opening is going to be less than 1/10th of an inch wider than a .223 comp, but overall an "enclosed" design.

But on a BB equipped rifle, hang whatever the hell you want off the front, its only the Featureless rifles that need to worry about what they are wearing

[highpower790]

DOes anyone know what the law is for a M1A flashider that has been reamed to national match specs?

[toby]

Have one made, there are millions of people with the know how and machinery, when you want something special off the self doesn't cut it.

[highpower790]

Already done.

It's a flash hider and your rifle will not be featureless.

forgot about them. its been so long since they have had barrels. I bought one a couple of years ago. I bought a muzzle brake copy on ebay for .556 and had a friend bore and rethread it for 5/8x24.
the cheaper copies on ebay are usually not heat treated, so you can rethread them.

http://www.ar15performance.com/barrels these have a 5/8-24 thread, to prevent "swelling"

now that makes me happy. In my lands far far from here, we can do anyhting, as long as its 16" oal barrel...if you have money for a c-mag, you can own it, AND use it!
