SR-25 Pattern Magazine

An SR-25, AR-10 or LR-308 pattern magazine is a type of detachable firearm magazine based on the original Armalite AR-10 "waffle" magazine design introduced in the late 1950s, used for .308 Winchester and 7.62×51mm NATO cartridges.

The design has been used on many AR-10 derivatives (generally referred to as AR-308 style rifles), for instance in the Knight's Armament SR-25 and DPMS Panther LR-308, as well as bolt-action rifles such as the Mossberg MVP .308, Ruger Precision Rifle and Q FIX. Aftermarket magazines are produced by Magpul, Lancer Systems, and others. Not all AR-308 rifles use magazines compatible with the SR-25 pattern. For example, HK417/MR308/MR762 uses a proprietary design. Notably, Armalite switched from their original pattern magazines to modified M14 magazines in 1996 with their new AR-10B model, but reintroduced their original (SR-25 pattern) magazine design with the AR-10A model in 2012.

Notable incompatible firearms

SR-25 pattern magazines are in general not compatible with rifles using Springfield Armory M1A pattern magazines, FN FAL pattern magazines, or HK41/HK91/ G3 pattern magazines. As mentioned, the AR-10B variant (produced since 1996) uses proprietary modified M14 magazines, while the AR-10A variant uses standard SR-25 pattern magazines. The Noveske Rifleworks N6 version prior to Gen 3 used AR-10B type magazines, but with the introduction of the N6 Gen 3, however, the design was changed to utilize the more common SR25-type. Rock River Arms LAR8 uses proprietary FAL style magazines. MKEK MPT-76 uses a proprietary design. As mentioned, HK417/MR308/MR762 uses a proprietary magazine.
