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

The Midwest Industries AR Muzzle Brake - 1/2-28 Two Chamber Brake will work with a Ruger 22LR rifle with muzzle threaded for 1/2x28.

by Hunter, Gear Expert, July 11, 2023
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.

Helpful Positive Review Midwest Industries AR Muzzle Brake: A+ by TomG, Verified Owner, November 18, 2024
Well, I've not actually fired the rifle with the break, but I have no doubt that what little recoil the 5.56 normally produces will be greatly diminished. I have the 7.62x39 version on a Kalashnikov and it works like a charm. If this 5.56 model holds...

Helpful Positive Review Best Recoil Reduction for the Price by Slonjo, Verified Owner, July 26, 2022
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 ...

Helpful Positive Review It does work.. somewhat by shootersdrive, Verified Owner, April 23, 2018
Does mitigate a little bit of recoil. I liked it because of the enhanced amount if flash i get from my barrel. It is also pretty loud which is a plus for me. Someone at the range thought i was shooting a .308 when i was only shooting .223 �. Do recom...
