My Buddie, John Allchin has come up with a new compensator designed just for the 10-22 bull barrels with a .920″ diameter. I suppose you not limited to the 10-22, any Long Rifle Barrel with a .920″ muzzle will accept this type of brake.
John is making them from T6 Aluminum, in two finishes, Matte Black anodized and Matte Silver anodized. Just thread the muzzle for 1/2″x28 and install. I am always looking for products like this that the big discount stores are not likely to carry, that way I am not competing head to head with the Marts.
You can learn more about this and other products at John’s site, http://allchingunparts.com/index.php
