What would be your ideal NJ legal muzzle device? Length? Diameter? Placement of holes and/or slots? Open or closed end? Do you want it to reduce recoil, muzzle rise or just look evil?
I am contemplating designing and having one manufactured. It will be long enough to make 14.5" barrels 16", and the threads will be 1/2" x 28 TPI. The sound and flash will not be controlled. It will be tested and found to NOT suppress the flash and it will be advertised that way to satisfy NJ laws.
