Great BCG!
Perfectly working BCG. Hard to find quality lefty BCG’s in the market and it’s worked fine.
USA Must for Lefty Shooters
This is great for those who shoot left handed. No blowback of gases or shells to the face. A must have option that you'll fall on love with.
United StatesStrong bcg
Needed this to complete my lefty build. I’ve had it for over a year now and I’ve put 2000+ rounds through it with no problem. I believe there is way more life in the BCG as well.
LH 5.56 build
Threw this in my left handed 5.56 build. Got about 300 rounds through it right now. Absolutely solid! No issues at all.
USGreat Left Hand AR BCG
