The Magpul Pmag Gen M3 Window 30RD 5.56x45 NATO Magazine uses a crush resistant polymer body. This tough Sand colored Magpul 30-round next-generation magazine for AR/M4 has modified dimensions to be compatible with more non Colt-spec platforms.  The extremely reliable Anti-tilt, self-lubricating follower prevents any dive while feeding. This Magpul Pmag Gen M3 Window 30RD 5.56x45 NATO Magazine uses a Long life USGI-spec stainless steel spring and has an over-travel insertion stop on the spine. Ribbed gripping surface and new aggressive front and rear texture for a solid grip every time. The bottom of the body has paint pen dot matrix panels for identification marking. A flared floorplate eases magazine handling and disassembly but is still sim enough for many double and triple pouches. The Magpul Pmag Gen M3 Window 30RD 5.56x45 NATO Magazine also comes with pop-off impact/dust cover for optional extra protection. This proven magazine has the added feature of the anti-glare translucent maglevel window on both sides of the body, as well as a painted indicator on the spring for an easy read on rounds remaining.
