Magpul PMAG D-50 AR-10 LR/SR Gen M3 308 Win 50rd Drum Magazine

The PMAG D-50 is a 50 round polymer drum for SR25 and M110 pattern AR-10 rifles in 308 Win and 7.62x51 NATO. It handles longer than SAAMI match loads such as M118LR, and it uses Gen M3 polymer construction that seats fully loaded on a closed bolt. Stainless steel internals resist corrosion and hold up to long term loaded storage.

A ratcheting loading lever takes spring tension off for easy hand loading, and an anti-glare window on the rear shows rounds remaining. It comes with a semi-rigid dust cover and comes apart with a flat blade screwdriver. The drum stands about as tall as a 25 round PMAG, so prone shooting is no different. It is made for 308 Win and 7.62x51 only, not 260 Rem or 6.5 Creedmoor, and it may not lock the bolt back on newer DPMS GII based rifles.
