THIS WILL NOT FIT THE SMITH AND WESSON RIFLE ALSO KNOWN AS THE S&W M&P 15 .22.
Please find the S&W Drum on the left hand side of our home page.

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.

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. If you attempt to order over the rounds required for your area you will be contacted and the item will be reduced and removed from your order.
