Thril PMX AR-15 5.56x45mm NATO 30rd Gray Polymer Magazine

The THRiL PMX is a 30-round detachable polymer magazine chambered in 5.56x45mm NATO and built specifically for AR-15 and M4 pattern rifles. Constructed around THRiL's polymer-matrix (PMX) formula, this magazine pairs impact-resistant polymers and elastomers for high performance and long-term durability. The clean gray finish sets it apart from standard black magazines on the rack or in the safe.

Inside the PMX magazine, an anti-follower works with a 17-4 stainless steel spring to deliver reliable feeding across extended range sessions. An elastomeric strike plate and an ergonomic housing profile round out the package, and the standard AR-pattern interface ensures drop-in compatibility with any AR-15 or M4 lower configured for 5.56x45mm NATO or .223 Remington.

Whether you are topping off a range bag, building out a backup rifle, or simply looking for a dependable high-capacity polymer magazine at a practical price, the THRiL PMX 30-round AR magazine delivers a lightweight, corrosion-resistant option for your everyday rifle.
