Factory rotary magazine designed and manufactured by Ruger, this magazine works well with the following factory original 10/22 rifles, SR-22 Rifle, 22 Charger Pistol, .22 LR Ruger American Rimfire Rifle and .22 LR Ruger 77/22 Rifle.
The maximum capacity for this rotary magazine is (10) rounds. Will only accept .22 Long Rifle caliber cartridges. Constructed of DuPont Zytel polymer for a strong resistance againt tear and wear.
The metal feed lips will despense thousands of rounds without any signs of wear, or jams. The Ruger rotary magazine is superior to conventional feeding systems because each cartridge lies in its own channel in the magazine. This arrangement prevents jamming by eliminating the overlap between cartridge rims found with stack-type magazines.
