AR15.22 & S&W M&P15.22 Drum Tips

Common Questions & Helpful Tips


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

Black dummy rounds: The plastic black dummy rounds that look like bullets are an important part of the drum assembly. They feed the ammo from the drum body to the tower. We do not recommend using them as real ammunition.

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.

Winding Rotor: Pulling the rotor counter clockwise and letting go without ammunition in the drum will most likely damage the drum.  It can cause the internal followers to break. You can purchase new followers if needed on our website.
