YouTube, HAS a few good posts showing, how to do it.
I like the 2 Witts, on my Varmint Guns ( a .22-250 and a 6 XC ) They help with, the muzzle Jump and about, 30- 35% less Recoil.
DE-Grease and Blue Loctite, the end of, Bbl and Screws as stated and TIGHTEN, the piszz outta them screws ( don't strip, threads tho ! ) There's been, NO "movement" on my Brakes,.. so far !
My .22-250 is showing me, exploded, Flying, Sage Rat parts with, 50 grain Bullets ( down loaded, a Tiny Bit ! ).
Be SURE to "Level" the Brake with, the Muzzle, as shown in the Vid.
