AR15 complete magazines for 3-Gun, PCC, and steel challenge competition are stocked here from Lancer, ETS, and PMAG, covering both standard 30-round capacity and extended options for divisions that allow them. Lancer's translucent L5AWM and AWM bodies let you visually track round count mid-stage, ETS magazines pair impact-resistant polymer with a low-friction follower for fast, reliable cycling, and PMAG-pattern magazines bring the battle-tested reliability 3-Gun shooters have relied on for over a decade. PCC shooters running pistol-caliber carbines in 9mm will find magazine options sized for their specific lower and magwell adapter setup, while 3-Gun competitors loading 5.56 for rifle stages get capacity and durability suited to repeated stage resets and rough field handling. Feed lip tolerances and follower geometry on these magazines are built to feed both hollow points and steel-challenge-legal ammunition without the nosedives or bolt-override issues that cheaper magazines introduce. Whether you're topping off spares for a 3-Gun weekend or building a case of PCC mags for a PCC-only club match, this lineup covers the capacity and durability competitive shooters need. Fast same-day shipping on most orders at Shooters Connection.
