Mission First Tactical Extreme Duty 30rd 223 Rem/5.56x45mm AR-15/M4 Black Polymer Window Magazine

The Mission First Tactical Extreme Duty (EXD) 30-round magazine is purpose-built for the AR-15/M4 platform and chambered in 223 Rem / 5.56x45mm NATO. Designed as an enhanced-duty upgrade over the standard STANAG-pattern magazine, the EXD is molded from Mission First Tactical's next-generation long glass fiber polymer for improved strength, durability, and corrosion resistance in hard-use environments.

This windowed variant uses transparent magazine windows to give a quick visual confirmation of ammunition level and round count. Internally, the magazine runs a long-life USGI-spec stainless steel spring paired with a four-way anti-tilt self-lubricating follower, supporting reliable feeding across the 30-round capacity. External ribs front and rear provide positive gripping surfaces for insertion and extraction.

Finished in black, the EXD is engineered for the AR15/M4 and is also compatible with a wide range of non-AR15/M4 platforms that accept the standard STANAG 5.56 magazine pattern. Made in the USA by Mission First Tactical.
