Common Questions & Helpful Tips
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. Removing any of the 5 dummy rounds will cause your drum to not function.
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. The manual provided will walk you through disassembling the drum to adjust spring tension to work with your firearm. It is also available HERE.
Bolt Drag: We have noticed that some 10-22's have higher cut lockups than others resulting in bolt drag. Test the drum in your rifle unloaded by pulling the bolt back to see if you are getting any bolt drag on the left feed lip (taller lip). If so, you can remove a small amount of material without affecting the performance of the drum.
Winding Rotor: Pulling the rotor counter clockwise and letting go will most likely damage the drum. It can cause the internal followers to break.
