Magpul’s PMAG 10/30 gives you 10-round compliance with a 30-round appearance. Designed for areas with 10-round magazine restrictions, the PMAG 10/30 features a proprietary lock plate that reduces the maximum capacity to 10 round. The lock plate is permanently secured in place by an aluminum rivet, and the lock plate tab is clearly marked for capacity. Like its 30-round counterpart, the PMAG 10/30 is optimized for durability and reliability. The bolt catch notch is redesigned to provide increased bolt catch clearance, and an overtravel 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.
