Recommended Ammunition:
Federal, CCI/Blazer, American Eagle. Use a round nosed bullet. Stay away from hollow points. Ammunition not listed will not feed well in our products.


Black dummy rounds: The plastic black dummy rounds are an important part of the drum assembly. They feed the ammo from the drum body to the tower. BDM does not recommend using dummy rounds as real bullets.

Spring Tension: If you come across feeding issues, the drum spring may be too tight causing ammo to rush up and out the tower. You may also have feeding issues if the spring is too loose. Spring tension may also be required to adjust to your rifle’s bolt speed. The manual provided will guide you through disassembly & assembly. The manual is also available as a PDF on our website.

Winding Rotor: Pulling the rotor counter clockwise and letting go will most likely damage the drum.  It can cause the internal followers to break.

Simply awesome, most reliable mag I have
Darren Mabe (Boise, ID) 3/31/2019 11:32 AM
Of all the 15-22 mags I have this one and my 10rd simply never fail. Even with standard velocity stuff. I find the loading to go quick with the thumb winder on the back. Its a little stiff to wind but once you get the hang of it, or wear a glove its quick and easy.
Long to fill - quick to empty :-)

I have a ceiner 22 conversion kit for my AR platform. I have three 50 round black dog mags. I use WalMart's best Federal 22 to feed the beast (love that ammo - price and performance). So far (about 5 boxes - 550 per)the only issue has been that one mag sticks a little in the mag well. A little dry lube fixed that. Great mags for an AR platform. I have also called Black Dog a few times to ask for advice on other issues - fantastic customer service. All round 5+ stars
Drum runs like a champ

I took it out of the box, loaded it with Federal bulk and proceeded to put all 50 rounds down range at a pace of about 1 round a second. I then put 20 Federal Auto Match in it and did the same thing. I fired another 30 or 40 rounds of whichever brand I grabbed at a slower pace. No issues. I also found it easy to load. Equipment: Tactical Solutions AR-22 LT upper on a DoubleStar lower.

I bought this drum for my Chiappa M4 and it worked flawlessly. It is a solid piece of thermoplastic, very well designed and constructed. Even though it looks big, it is not that heavy for the amount of parts involved and the size. It takes a little trying to learn how to load it so the ammo stars pick up the rounds without skipping but once you learn it, it is a piece of cake loading. I have not taken it apart but hopefully I won't need for a while. I only used the recommended ammo American Eagle and CCI AR Tactical without any feeding issues. I can't tell you if other types of ammo would work or not. I am very pleased and recommend the product.
A full-auto blast!

I bought one of these, and it worked like a champ out of the box on my M16 w/.22 Kuehl/Ciener upper. 50-rd mag dumps, perhaps one jam every drum or two. Liked it so well I just bought two more!
