MSAR XM17 E4 AR15 30 Round Black Polymer Magazine - 5.56 / .223 / 300 BLK Caliber

MSAR knows how important it is to avoid being caught empty handed, which is why we developed the crew fifth generation, 30 round magazines. Re-engineered for a precision fit on most rifles *Compatible with Bushmaster, Colt, Daniel Defense, DPMS, DS Arms, FNH SCAR, Series HK 416, Rock River Arms, Ruger, Smith & Wesson, & Windham Weaponry AR-15 type .223 rifles.

In an effort to remain compliant with recent regulations, and continue to accommodate our customers, MSAR has developed a new line of competition magazines. These magazines are the same size as traditional 30 round magazines, but are pinned to only accept 5, 7, 9, or 10 rounds. The matte black, green, and tan magazines are made from the same impact modified UV resistant polymer as the follower, and offer a more economical cost option for consumers.

The new E4 magazine is compatible with most standard .223/5.56 AR-15 style rifles. Flame retardant and chemical resistant, this material also has low moisture absorption, low deformity properties making it ideal in extreme conditions.

• A unique triangular riser allows for positive contact in all host weapons with a last round hold open.
• Molded ridge present to prevent over travel of the magazine when inserting into host weapon.
• A corrosion resistant body spring is used for maximum durability.
• Floor plate with raised rib for additional grip, designed from impact modified UV resistant polymer.
• Self adjusting follower designed from impact modified UV resistant polymer.
• Ribbed for increased grip-ability.
