THRiL PMX AR-15 .223/5.56 30rd Flat Dark Earth Magazine

The THRiL PMX is a high-performance 30-round detachable magazine built for AR-15/M4-pattern rifles chambered in 5.56x45mm NATO (also compatible with .223 Remington). It is engineered around THRiL's proprietary polymer-matrix (PMX) construction, combining impact-resistant polymers and elastomers for exceptional durability under hard use.

Internally, the PMX magazine uses a 17-4 stainless steel spring paired with an anti-tilt follower to deliver smooth, reliable feeding round after round. An elastomeric strike plate protects the feed lips from impact damage, while the ergonomic body with a textured Flat Dark Earth finish provides a confident grip for reloads in any condition.

Made in the USA, the THRiL PMX is a drop-in upgrade for any standard AR-15, M4, or M16-pattern carbine or rifle. Whether you run it as a duty, range, or defensive magazine, the PMX brings modern polymer engineering to the familiar STANAG footprint.
