Questions & Answers
I imagine it will fit on the Ruger .22LR rimfire rifle since the threaded end of the ruger barrell is 1/2 -28? Expert Answer

Does it matter if the MI logo is on top or bottom of barrel after tightening? Expert Answer

The MI logo can be oriented at the 12 or 6 o'clock position and still retain full functionality. You can always use additional shims in order to time the muzzle device to your liking.

I've tried several different muzzle devices at this point. VG6, RRA Varmint, RRA Hunter, Trybe, etc. On my Ruger AR556 this is the one that limits the recoil and muzzle rise the best. I use this one for Automatic Rifle competitions at my club and it ...
