Gen M3 PMAG 300Black 20 Rds Magazine Black

Description

MAGS BUILT TO OUTRUN STOCK.

Stock 5.56 mags choke on 300BLK. This doesn’t. Gen M3 PMAG 300 Blackout 20 Rds – engineered from the ground up for 300 BLK geometry. Not a converted 5.56 mag. Not a compromise. A dedicated platform. Built to feed wide, heavy, and long projectiles without tilt, without drag, without excuses.

POSITIVE FEEDING. FASTER FOLLOW-UPS.

300 Blackout demands more than a standard follower. This delivers. Ribbed interior and redesigned anti-tilt follower controls the round’s angle from stack to chamber. Constant-curve internal geometry prevents nose-dive with 220gr subsonics and fat 150gr supers. Long-spring stainless steel spring – consistent pressure, no fade. Positive, tactile feeding shot after shot. Every jam you don’t clear is time you gain. Victory is still earned.

BUILT FOR HARD USE. ENGINEERED TO OUTPERFORM.

Impact-resistant polymer body – next-gen Magpul formula. Crushes, drops, recoil, heat – holds shape. Aggressive front and rear texture for positive grip when wet, gloved, or bloody. Over-travel stop prevents over-insertion on closed bolt. Low-profile floorplate but compatible with Ranger plates. Windowless sealed body keeps sand and carbon out. Rated for subsonic and supersonic 300BLK. Built to hold up under hard reloads. Every unit sealed and protected. Arrives ready to load.

CONTROL UNDER PRESSURE. NO COMPROMISES.

20-round footprint – perfect balance of capacity and maneuverability. Shorter than 30 – ideal for prone, bench, vehicle, and suppressed work. Doesn’t print. Doesn’t snag. Keeps rifle flat in the bag. Optimized for suppressed shooting – reduced length clears cans and tripods. Competition, hunting, and home defense ready. All factory safeties retained. No fitting. No tuning.

DROP-IN DOMINANCE. ZERO FITTING. ZERO EXCUSES.

Fits all AR-15 / M4 platforms chambered in 300 AAC Blackout. Mil-spec magwell compatible. Seats positively on closed or open bolt. No modifications. No filing. Just seat and send. Also runs .223/5.56 in an emergency, but optimized for 300BLK – we recommend dedicated use.
