When purchasing Black Dog Machine or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

Black Dog Machine’s 32 rounds polycarbonate magazine is designed to work with a number of .22LR AR-15 style firearms. Made from durable polycarbonate these magazines feature stainless steel feed lips for improved lifespan. Loading all 32 rounds is also made easier by the built-in thumb pull down tab. (Never use this feature without loading ammo into the magazine. Sliding the thumb assist down the magazine then releasing the thumb assist back to original position will most likely damage the internal pieces. If this happens, the Warranty is voided.) This magazine works with Atchisson/Ciener, CMMG (older models), Model 1 Sales, Spikes Tactical, Tactical Solutions, Target Master Conversions & other AR-15 .22LR dedicated uppers and conversion units.

Please note that this magazine does not work with: CMMG (evolution), Sig 522, KelTec SU22 & PLR22, Colt, DPMS or S&W M&P15-22.
