The 30-round, Extreme Duty 5.56 Polymer Magazine from Mission First Tactical utilizes the next generation of long-glass-fiber polymer to provide a magazine that is 50-percent stronger and three times more impact resistant than traditional glass-filled nylon. With front and rear surfaces ribbed for a better grip, a USGI-spec stainless-steel spring, a four-way anti-tilt self-lubricating follower and an oversized bolt catch, this is a magazine designed around easy accessibility, and lasting longevity. Though obviously intended mainly for the AR-15/M4 platform, Mission First Tactical assures its compatibility with a wide range of differently platformed firearms. Boasting an MSRP of only $12.99, which includes a lifetime warranty, the Extreme Duty 5.56 Polymer Magazine is priced extremely competitively with the rest of the market.
