Black Dog Machine 10/22 50rd Drum

***Check for bolt drag before using your drum!***

Bolt Drag: You will notice one side of the feed lips is taller than the other. We have added this material to accommodate those rifles built with higher cut mag wells. Depending on your brand of rifle, you might have a lower cut mag well. This may cause “bolt drag”. Insert the drum into your rifle unloaded. Slowly pull the bolt back a few times to see if you are getting any bolt drag, mostly on the left feed lip (taller lip). If so, you can remove a small amount of material without affecting the performance of the drum.

Drum Features:
Built with an interchangeable feed tower. You can easily disassemble the drum, slide your 10-22 tower out and replace it with the new Black Dog AR-22 or S&W.22 feed towers.

Material: Polycarbonate

We do not guarantee that the drum will work in full-auto setups. However, many customers report that with a little fine tuning they can get the drum to work in full-auto.

MANUFACTURER'S TIPS:
-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.

- I CHECKED FOR BOLT DRAG AND AM STILL HAVING FEEDING ISSUES.
SEE LAST TWO PICTURES OF A SMALL MODIFICATION YOU MIGHT NEED TO MAKE. YOU WILL SEE A PICTURE OF THE FEED LIP WITH A "ROUNDING" MODIFICATION, THE LAST PICTURE IS A CLOSE UP WITHOUT THE MODIFICATION. YOU ONLY NEED TO DO THIS TO THE END THAT HAS THE ARROWS POINTING TO IT.

 
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.

Clear rubber bands: Each drum is assembled with one clear rubber band and two extra bands taped to the inside of the drum box provided.

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.

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

High capacity magazines are restricted in certain states: California, Colorado, Connecticut, District of Columbia, Illinois, Hawaii, Maryland, Massachusetts, New Jersey, New York , Vermont and Washington may be restricted in other municipalities. It is the customer's responsibility to be aware of and abide by all applicable local laws.
