These magazines for our new 7.62x39mm Rifle and Upper are similar the 30 Rd. .223 magazine, but due to larger 7.62x39 case size hold only 26 rounds. Other models are blocked to the indicated capacity within the same size dark grey hard anodized aluminum shell. They include anti-tilt followers, and the Bushmaster logo on the base plate. All can be disassembled for cleaning.
