Overview

The Magpul PMAG 25 LR/SR GEN M3 is the default magazine for SR-25 / DPMS-pattern AR-10 rifles in .308 Winchester, 7.62x51 NATO, and 6.5 Creedmoor. It fits the dominant large-frame AR ecosystem, including Knight's Armament SR-25 and M110, Aero Precision M5, Daniel Defense DD5, LMT MWS, POF Revolution, Sig 716, Springfield Saint Victor .308, Ruger SFAR, JP LRP-07, and most LaRue OBR variants.

Magpul's GEN M3 design uses impact- and crush-resistant polymer to prevent the geometry drift that plagued early-generation SR-25 polymer magazines. The four-way anti-tilt follower and constant-curve feed path handle the longer .308-class cartridge geometry without the bolt-over-base failures common to repurposed AR-15-style internals.

At roughly $22 street, the PMAG 25 undercuts most metal SR-25 magazines by half while matching or beating them on real-world reliability. Practical advice: buy these in 5-packs for any AR-10 build, mix loaded mags between range training and home use, and avoid the older non-LR/SR PMAG variants which were AR-15 only.

Key Features

  • 25-round capacity for .308 Win / 7.62x51 NATO / 6.5 Creedmoor
  • SR-25 / DPMS Gen 1 pattern fitment across most large-frame AR-10 platforms
  • Steel-reinforced feed lips resist deformation under long-term loaded storage
  • Four-way anti-tilt polymer follower with self-lubricating geometry
  • Stainless steel spring with extended service life
  • Paint pen dot matrix and removable floorplate
  • Designed to remain loaded indefinitely without spring fatigue

Pros

  • +Default standard across the SR-25 / DPMS pattern AR-10 ecosystem
  • +Half the price of comparable metal AR-10 magazines
  • +Steel-reinforced feed lips solve early polymer SR-25 mag failures
  • +Identical handling and reload muscle memory as AR-15 PMAGs
  • +Wide compatibility: KAC SR-25, Aero M5, DD5, LMT MWS, Sig 716, Ruger SFAR, POF Revolution

Cons

  • Does not fit AR-15 magazine wells (large-frame only)
  • Some early Armalite AR-10 rifles use a different proprietary mag pattern
  • Slight bolt-over-base risk on extreme overpressure handloads
  • Only available in black
