* PLEASE NOTE: PMAG 5 7.62 AC magazine is for the 308 Winchester and similar sized cartridges. Rifles that use smaller or larger cartridge cases will require the customer to separately purchase an AICS pattern compatible magazine of their choice.

The Hunter American stock is supplied with a revised PMAG 5 7.62 AC magazine, easily identifiable by its brown lock plate and follower. Earlier generation PMAG 5 7.62 AC magazines can be identified by their green lock plate and follower. Due to some of the design features and geometries of the Ruger American Rifle®, the new brown follower and spring design was created to improve function with non-.308 based cartridges, such as 6.5 Creedmoor, in that platform, which also resulted in an all-around performance improvements in other calibers and PMAG AC/AICS compatible platforms. The earlier green follower PMAG AC will still perform well in the Ruger American Rifle® with the .308 Winchester based family of cartridges, but for best results with 6.5 Creedmoor and other non-.308 based cartridges in the Ruger American Rifle® in the Hunter American stock, the new brown follower PMAG 5 7.62 AC magazines are recommended. Non-.308 based cartridges may also not perform ideally in the Ruger American Rifle® in the Hunter American stock with 10 round PMAG 7.62 AC magazines, regardless of generation, due to bolt and interface geometry.
