Description
MAGS BUILT TO OUTRUN STOCK.
Stock steel SR25 mags dent, bind, and weigh you down. This doesn’t. Gen M3 PMAG DPMS/SR25/LaRue OBR 20Rds – purpose-built for large-frame ARs. Not a scaled-up 5.56 mag. A dedicated .308 Win / 7.62 NATO platform. Engineered for DPMS LR308, SR-25, LaRue OBR, KAC, and all SR25-pattern lowers. Built to feed long, heavy .308 without tilt, without drag, without excuses.
POSITIVE FEEDING. FASTER FOLLOW-UPS.
.308 demands force and geometry. This delivers both. Constant-curve internal design with next-gen anti-tilt follower controls heavy 147gr to 175gr projectiles. Four-way anti-tilt follower – contacts front, rear, and both sides. Eliminates nosedive under recoil. Long-life stainless steel spring – constant force from round 1 to 20. No fade under full stack pressure. Positive, tactile feeding even when dirty. Every malfunction you don’t clear with a .308 rifle is power retained. Victory is still earned.
BUILT FOR HARD USE. ENGINEERED TO OUTPERFORM.
Impact-resistant polymer body – Gen M3 enhanced formula. Crushproof, drop-proof, recoil-proof. Lighter than steel by 40% – run faster, carry more. Aggressive front and rear texture for positive grip when wet, gloved, or under stress. Over-travel stop prevents over-insertion on closed bolt. Ribbed lower section for mag-pull grip. Sealed body keeps sand, mud, and carbon out. Rated for 7.62×51 NATO and .308 Winchester. Paint pen dot matrix for mag marking. Every unit sealed and protected. Arrives ready to load.
CONTROL UNDER PRESSURE. NO COMPROMISES.
20-round standard – perfect balance of capacity and prone performance. Shorter than 25rd – doesn’t hit the dirt in prone, bench, or vehicle. Keeps large-frame AR flat. Ideal for precision, hunting, battle rifle roles. Handles supersonic pressure without swelling. Large-caliber control starts in the mag. Competition, precision, and battle rifle ready. All factory safeties retained.
DROP-IN DOMINANCE. ZERO FITTING. ZERO EXCUSES.
Fits all DPMS LR308-pattern, SR25, LaRue OBR, KAC SR25, Bushmaster .308 ORC, Remington R-25, JP LRP-07. Will NOT fit Armalite AR-10B, Springfield Saint Victor .308, or M110A1. Mil-spec magwell compatible. Seats positively on open or closed bolt. No modifications. No filing. Just seat and send.
