Nice for lightweight build - Adaptive Tactical LTG Lightweight Tactical AR Grip

I put this on a tnarms 80% hybrid lower that's the platform for an 18" lightweight .223/5.56 at-15 with aluminum upper. Just saving weight in a few areas where I can, knowing to keep a decent chunk of metal around my bcg. Lightweight is cool, but reliability is everything.

Optics Planet is always a pleasure to deal with.
