Magpul PMAG 30 GEN M3 Window 5.56 NATO - AR-15 Magazine - MCB

Know where you stand without pulling the magazine. The Magpul PMAG 30 GEN M3 Window brings MagLevel translucent windows and a high-visibility indicator coil to the world's most reliable rifle magazine, giving AR-15 and M4-pattern shooters real-time round count confirmation without interrupting the shooting sequence.

The Magpul PMAG 30 GEN M3 Window is a 30-round 5.56 NATO polymer magazine for AR-15 and M4-pattern rifles, featuring dual translucent MagLevel windows with a painted indicator coil, constant-curve geometry, and anti-tilt follower for reliable feeding in any condition.

Four features define the PMAG 30 Window's position as the standard for windowed AR-15 magazines. Dual MagLevel translucent windows on both sides of the body — paired with a high-visibility painted indicator coil on the spring — provide continuous and accurate round count confirmation without removing or tilting the magazine. Constant-curve internal geometry and the self-lubricating anti-tilt follower ensure smooth feeding from the first round to the last in mud, sand, cold, and heat — conditions where lesser magazines fail. Crush-resistant GEN M3 polymer construction and reinforced feed lips deliver reliable operation across M4, M16, AR-15, HK 416/MR556, M27 IAR, and other platforms that accept STANAG-pattern magazines. Aggressive texturing on the body and slimline removable floorplate complete the package for positive control and easy maintenance.

Compatible with AR-15, M4, M16, HK 416/MR556, M27 IAR, and other STANAG-compatible platforms in 5.56 NATO and .223 Rem.
