Extreme Duty Window Magazine

Dec. 31, 2019

Designed for the AR15/M4 but allowing use with a wide range of non-AR15/M4 platforms, the Extreme Duty Window Magazine is currently available in Black and Scorched Dark Earth, and will also be available in colored windows and decorated units in the future.

Utilizing new material technology and manufacturing processes for enhanced strength, durability, and reliability, the Extreme Duty Window Magazine exceeds demanding military performance specifications. Durable dual-side anti-glare transparent windows, numerical markers, and high visibility indicator coil on the spring allow for quick visual identification of the approximate number of rounds remaining.

Manufactured using the newest material technology and processes, the magazines with their next-generation long glass fiber polymer construction offer the trifecta of perfection in structural performance: strength, durability, and stiffness. The stiffness allows the magazine to maintain its integrity without additional weight with an additional benefit of top performance even at elevated temperatures. The longer length reinforcing fibers produce increased strength, prevent deformation, and polymer fatigue. Additionally, the Extreme Duty Window Magazines offer increased durability through a more efficient energy transfer between the polymer and the longer fiber filaments during an impact. The long-life USGI-Spec stainless steel spring is corrosion resistant. The four-way, anti-tilt, self-lubricating follower keeps the rounds aligned and makes mag feeding consistent and reliable, while virtually eliminating jams.

Confidence in handling the Extreme Duty Window Magazines is a piece of cake, even during weather or duress. The front and rear of the gripping surface are ribbed for a positive grip, even with gloves. An oversized bolt-catch provides enhanced reliability of the bolt catch operation. The flared floor plate allows for an easier grip in handling, extraction, and one-hand reloads. Wrapping up the multiple benefits to the newest addition to the MFT magazine line is a paint pen dox matrix to allow for easy marking and identification of magazines. It also features tool-less disassembly with the double floor plate safety release tabs.

Mission First Tactical Extreme Duty Window Magazines are built for hard shooting, extreme treatment and shooting conditions, and comes with a Lifetime Warranty.
