If you have a Ruger 1022 in calibre 22 l.r. and want to install a muzzlebrake without threading the barrel, we’ve got the solution for you.
You don’t necessarily need installing a muzzlebrake just because of the recoil, though it’s perfect if you wish a more harmonious appearance.
The thread is: 1/2-28 as 1/2-28 is the standard thread used in/for an AR-15, so this is the most common thread on muzzle brake.
You can keep the front sight.
You skewer the nipple/adaptor over the barrel and then lock it using two countersunk screws at the bottom.
