The Magpul PMAG GEN M3 is a 25-round magazine for AR-10 and SR25 pattern rifles chambered in .308 Winchester / 7.62x51mm NATO. Built for shooters who demand reliability without compromise, this magazine combines proven Magpul engineering with practical field features that work whether you're at the range, hunting, or training. The constant-curve body and anti-tilt follower deliver smooth, reliable feeding with every round, while the impact and crush-resistant polymer construction handles the realities of tactical use and outdoor conditions.
What sets the GEN M3 apart is its transparency and handling. Translucent MagLevel windows on both sides let you see your round count at a glance — no guessing on the line when you need to top off. A painted indicator on the spring adds another visual reference, and the paint pen dot matrix on the body helps you quickly identify different loads when you're juggling ammunition types. The flared floorplate and aggressive texture on the front and rear give you something positive to grab, even with gloved hands or in low light.
Made in the USA, the PMAG GEN M3 is engineered specifically for SAAMI-spec .308 Winchester ammunition and is compatible with a wide range of AR-10 variants, including models from Armalite, Colt, LaRue, KAC, LMT, LWRCI, POF, Ruger, S&W, and others. Check compatibility below if your rifle is less common — some older designs and piston-driven platforms use different magazine patterns and won't work with this one.
