Designed to live up to the \u003cstrong\u003eGunner\u003c\/strong\u003e name, this BCG is purpose-built for fast, smooth, competition-ready AR-15 platforms.\u003c\/p\u003e\n\u003cp\u003eAt just \u003cstrong\u003e8.5 ounces complete\u003c\/strong\u003e, this lightweight carrier reduces reciprocating mass to improve cycling speed, reduce recoil impulse, and enable faster follow-up shots.
