There are many types of magazines for the Ruger 10/22. The standard 10/22 ships with a black 10-round polymer rotary magazine, the BX-1. Ruger has also introduced a transparent polycarbonate version ("40th-anniversary edition") of the BX-1 called the BX-1CLR, as well as a 1-round version for training and a 5-round version for states or countries that restrict magazine capacities. In 2011–2012, Ruger came out with the BX-25, a curved 25-round box magazine with a black composite frame and steel feed lips, as well as the 15-round BX-15 box magazine for states that restrict magazine capacities. Aftermarket options include 25-, 30-, and 50-round box magazines; 50-round teardrop-shaped rotary magazines, and 50- and 110-round drum magazines.
