Thril PMX AR-15 Magazine 30rd 5.56/.223 Black Polymer

The Thril PMX 30-round magazine delivers reliable feeding for AR-15 and M4 platforms in 5.56x45mm and .223 Remington. This black polymer magazine features anti-tilt followers and reinforced feed lips to ensure consistent performance across extended shooting sessions.

What Makes This Different

The PMX magazine incorporates a dual-spring system that maintains consistent tension throughout the entire capacity range. Unlike standard GI magazines that can experience feeding issues when fully loaded, the PMX design reduces spring fatigue and maintains reliable function. The polymer construction offers 40% weight reduction compared to steel magazines while providing superior impact resistance.

Field testing demonstrates consistent feeding across various ammunition weights from 55-grain to 77-grain projectiles.
