Overview
The ProMag RM40 is a 40-round detachable magazine designed for the AR-15 platform. It is constructed from durable black DuPont Zytel polymer and features a unique roller follower system that reduces friction to enhance feeding reliability. The magazine utilizes anti-fatigue chrome silicon springs to maintain consistent upward pressure, allowing the magazine to be kept loaded for extended periods. This high-capacity design provides sustained fire capability without the bulk of a drum magazine, making it suitable for tactical training and range use.
