Black Dog Machine of Middleton, Idaho has some very interesting and innovative products for shooters, one of which is their new fifty-round drum magazine shown here. It is easy to load, and has proven to be one hundred percent reliable. The drum is made of a high-grade plastic, just like their twenty-five round stick magazines. The drum weighs just slightly over one pound, and protrudes out the bottom of the weapon roughly the same amount as the twenty-five round magazine.

The Black Dog Machine drum will fit and function with the Tactical Solutions, Atchisson/Ciener, Model 1 Sales, and Spikes uppers, and also in the Kel-Tec PLR-22 and SU-22, as well as the Sig 522. I have only tested it with the Tactical Solutions upper and the Kel-Tec PLR-22, and again, in those it functioned perfectly.  I also saw a video in which the drum was used with a full-auto .22 Long Rifle M-16, and again it ran perfectly. You can see that YouTube video here.

The Black Dog Machine drum magazine is a great idea, and a welcome addition to those firearms for which it will fit and function. Not much more that I can say about this product, except that it works, works very well, and I highly recommend it.

UPDATE:  Since reviewing this AR-15 magazine about three weeks ago, Black Dog has now introduced this drum magazine for the Ruger 10/22 rifle. It works and operates just like the AR magazine, but will work in any firearm that uses the Ruger 10/22 style magazines. I tried this mag in my 10/22 Tactical, and it fits and functions perfectly. Lots of firepower, and lots of fun!
