Crazy sound reduction - Guntec USA AR-15 Muzzle Comp w/QD Blast Shield

I shoot 556 rounds indoor, which can become incredibly annoying. This md really does push all gas and sound forward and even at the indoor range it was much more pleasant to fire. FYI - THIS WILL WORK ON ANYTHING THAT USES A 1:2x28 thread pitch!!!!! Don’t let them tell you otherwise. 22lr is a SMALLER projectile that uses the same thread as ALL standard AR. On a 22lr this will run fantastic
