Mission First Tactical has supplemented its full line of synthetic AR-15 magazines with 10- and 20-round options for the larger AR-10/SR-25/M110 platform. Optimized for use with SAAMI-spec .308 Win. and 7.62 NATO ammunition, the Extreme Duty Polymer Mag 7.62x51 NATO detachable box magazines are built from durable-but-light long-glass-fiber polymer and employ a corrosion-resistant stainless-steel magazine spring.
An anti-tilt follower ensures proper orientation of the ammunition for reliable feeding into the firearm, and a paint pen dot matrix on the bottom of the floorplate allows the magazines to be differentiated for quick identification. Price: $23 (10-round), $25 (20-round). For more information, visit missionfirsttactical.com.
