Material: Polycarbonate & Glass Filled Nylon
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.

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