flash supressors

The AR180B has an integral muzzle brake. This means that the muzle brake is part of the barrel. In order to add a flash supressor you must thread the barrel the AR180B. To do this you may or may not have to remove the barrel from the reciever.

WARNING!! Please read the following before doing anything to your rifle!!

Do not cut the barrel too short! The length of a barrel is basically defined as "from the face of the bolt to the end of the rifling." By this definition the AR10B barrel is only 18 1/4 inches (there is only 18 1/4" of rifling). When threading the AR180B barrel for a flash supressor BE SURE that the barrel length with no flash suppressor atatched is 18.5" inches or over. If you fail to do so and the barrel is shorter that 18.5" you have just created a prohibited firearm. 1/4" will land you in prison.

Where you can buy one all depends on what you thread the barrel for. If you thread it for standard AR flash suppressors (28 by somethign or other), then you can find them anywhere. Try Wolverine supplies, TSE, and so on. Any place that sells AR15 parts will work.

I highly recomend fellow CGN member Rooster33's Phantom flash supressor. It has little to no flash at all! Exellent for night vision optics and looks sweet at Natalie Portman's ass, but less jewish.

Have you threaded the barrel?

I am going to do the same thing pretty soon. Do I need to know the thread size for the gunsmith or is it a universal size? I have a USGI flash hider and crush washer.

But that's cause it's modified to be that length that makes it prohib, right?

i.e. the Colt Commando length uppers are legal?

Chopping a non-restricted barrel to less that 457mm would make it prohibited. A restricted may have any size barrel on it because it it already in that class.
