The PMAG 10/30 AR/M4 GEN M3 is a 10-round polymer magazine for AR15/M4 compatible weapons chambered in 5.56x45 NATO/.223 Remington. It was designed for users who reside in areas with magazine capacity restrictions but desire a standard 30-round magazine form. Built in-line with our other PMAGS, the PMAG 10/30 provides the same next-gen impact and crush resistance, constant curve geometry, and long-life stainless-steel spring to ensure smooth feeding. Weve added a proprietary lock plate that reduces the maximum capacity to 10 rounds, and its permanently secured by an aluminum rivet. A lock plate tab thats clearly marked for capacity is also included. With the standard 30-round magazine form, the PMAG 10/30 maintains mag pouch compatibility while complying with local restrictions. The PMAG 10/30 includes other features found throughout the GEN M3 line. Its redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, while an over-travel stop on the spine helps ensure the magazine will not over-insert on compatible weapons. Low profile ribs and new, aggressive front and rear texture give positive control of the PMAG 10/30 in all environments, and a paint pen dot matrix located at the bottom panel of the body allows for easy marking for identification. Not designed or intended to be modified in any way.
