Mag Mft Extreme Duty .308

The Mission First Tactical Extreme Duty .308 magazine is a purpose-built AR10/SR25/M110 rifle magazine engineered for shooters who demand reliability under real-world conditions. Whether you're running a precision rifle at distance, working through a training course, or deploying a modern .308 platform, this magazine combines military-grade durability with practical features designed to keep you in the fight. Built from advanced long glass fiber polymer, it handles temperature extremes, UV exposure, chemical contact, and impact without degradation—the kind of resilience you expect from gear designed to military specifications.

What sets the Extreme Duty apart is its balance of ruggedness and usability. The clear body lets you see your round count and ammunition type at a glance, critical for fast magazine changes or load verification in the field. A ribbed front and rear grip surface gives you purchase even in wet conditions or heavy gloves. The oversized bolt catch works smoothly with AR10-pattern upper receivers, and the flared floor plate seats positively every time. The four-way anti-tilt follower self-lubricates, so you won't need to baby the magazine or worry about sluggish feeding in cold weather.

Inside, a long-life stainless steel spring maintains consistent pressure cycle after cycle, and tool-less disassembly with dual floor plate safety release tabs makes field cleaning and maintenance straightforward. A paint pen dot matrix on the body is practical for marking loads or serial tracking. This is the magazine you reach for when mag reliability matters as much as barrel accuracy—built to feed .308 Winchester and 7.62×51 NATO ammunition consistently in the AR10, SR25, and M110 platforms.
