The original Ruger BX-25 Magazine was designed from the ground up, in-house at the Ruger factory, for flawless function and reliability in any Ruger 10/22 rifle or carbine. A rugged polymer body and follower make the magazine capable of handling prolonged use and almost any environmental condition. The steel magazine feed lips are engineered to withstand thousands of rounds without significant wear, drastically reducing ammunition feeding-related malfunctions and solving a problem that has plagued increased-capacity 10/22 magazines since their inception. The BX-25 magazine's 25-round capacity and excellent functional reliability are certain to make any trip to the range more enjoyable, with greater time spent shooting and less dedicated to clearing malfunctions and reloading.The BX-25x2 is a 50 round factory magazine for the Ruger 10/22. This magazine is essentially two BX-25 magazines molded into one, not just screwed, bolted, or glued together. The middle is a single piece molded into opposite facing BX-25 magazines, doubling the capacity of the original.Each magazine comes with one factory dust cover.
