The Magpul PMAG 20 AR/M4 GEN M3 brings the legendary reliability of the GEN M3 family into a compact, 20-round profile. This next-generation polymer magazine is designed for AR15/M4 platforms but features an expanded compatibility range, functioning flawlessly in the HK 416, MR556A1, M27 IAR, British SA-80, and FN SCAR MK 16/16S.Engineered with advanced material technology, the GEN M3 incorporates a long-life stainless steel spring and a four-way anti-tilt, self-lubricating follower for consistent, smooth feeding. Its compact 20-round size is ideal for prone shooting or bench rest applications where a lower profile is required. The magazine also features an over-travel insertion stop on the spine to prevent over-insertion and a redesigned bolt catch notch for increased clearance. With aggressive front and rear texturing and a paint pen dot matrix for easy identification, the PMAG 20 GEN M3 is the gold standard for tactical and competitive use.
The PMAG 20 AR/M4 Gen M3 delivers a compact 20-round profile with the same proven feeding geometry, anti-tilt follower, and crush-resistant polymer as the rest of the Gen M3 family. Ideal when you want a shorter magazine without sacrificing reliability—built to feed smoothly, survive hard use, and perform when it matters most.
