SEE TIPS BELOW IF YOU ARE EXPERIENCING FEEDING ISSUES.
***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.
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.
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.
-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.

Well mine jammed every 3 shells I thinks its a feed issue i was using round nosed Federal rounds, I hope i can figure it out. Also are you planning on making a tower for that model with the metal lips? I do not want mine to ever get worn out.is there a way to test the feeding with out shooting? I am going to disassemble and loosen it a bit see if it helps.

This is by far the best 10/22 drum mag on the market. feeds like a beauty queen and loading is much easier than others ive had. The only complaint i would have are the feed lips and back tab. both are starting to chip and break off(back tab but fixed myself). if you guys put out a 10/22 drum tower with steel lips and a metal tab, i would buy 10 more of these things. still gets 5 stars for an awesome magazine. thanks
THE BEST MAGAZINE EVER!!!!!!!!

I was a little skeptical at first because I have used other large capacity mags that turned out to be jam babies. But this hasn't let me down. Only FTF issue was because ammo was sticky. Otherwise I load it and empty it. Good times all around. How about a 200 round drum guys?
