The Black Dog AR 50 round drum magazine will fit Ceiner/Atchisson, Mod 1 Sales, Spike’s Tactical, Tactical Solutions, Target Master, Kel Tec PLR-22 and SIG 522 rifles. It will not work with the Ruger 10/22, Puma PPS50, M261, DPMS kits, Carbon 15 or S&W M&P 15. This is a dependable and quite rugged polycarbonate unit made of the same material as the Black Dog box magazines. This magazine is guaranteed to work in semiauto, but not for fully auto. However, users report that it is possible to fine tune the Black Dog AR 50 round drum magazine for fully automatic use.
