I have been asked on occasion to make a non standard thread. This no problem just give me the thread pitch and I can make it. Specify Stainless or Blue and caliber. If you would like the break tappered to your barrel dia. include that dimension.
Custom muzzle break 1 1/8″ dia. And 7/8” dia
Thread ½ x 28 and 5/8 x 24 standard. Custom threading available
For caliber please specify
If you want taper to match barrel, specify muzzle diameter
