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.

Cartridges compatible with SR-25 pattern magazines
Some cartridges are dimensionally similar to .308 Winchester to fit into SR-25 pattern magazines, its not uncommon for the cartridges to have the same rim diameter, which allows the use of the same bolt
