Modifying muzzle brake

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

Modifying muzzle brake

Post by J D D »

I have a 45 acp carbine threaded .578x28.
I just got a 45k Omaga out of jail. I attach it via a piston and fix barrel device. Frankly it’s a pain in the but removing my ASR mount to do it. I use it for sun sonic 300 black out . Would it be possible to re thread a 1/2x28 9 mm single chamber ASR muzzel break and bore it to .458 so I can just use my ASR mount . Will just a .578x28 tap do it
