Magpul MAG1183-BLK PMAG 10/30 AR/M4 GEN M3 is a polymer magazine for AR15/M4 compatible weapons. It is designed for areas with magazine capacity restrictions but desires a standard 30-round magazine form. Built in-line with other PMAGS, the PMAG 10/30 provides next-gen impact and crush resistance, constant curve geometry, and a long-life stainless-steel spring to ensure smooth feeding. A proprietary lock plate reduces the maximum capacity to 10 rounds and is permanently secured by an aluminum rivet. A lock plate tab clearly marked for capacity is included. With the standard 30-round form, the PMAG 10/30 maintains mag pouch compatibility while complying with local restrictions. Not designed or intended to be modified in any way. Made in the USA.
