Frequently Asked Questions

Can this drum magazine be used with hollow point ammunition?

No. The KCI USA 10/100 drum magazine is specifically designed for full metal jacket (FMJ) or standard ball ammunition. Using hollow point rounds can cause feeding malfunctions and may damage the internal follower system. Stick to standard pressure FMJ loads for reliable performance.

Will this magazine work with my AR-15 pistol or carbine?

Yes, this drum magazine is compatible with any AR-15, M16, or M4 pattern firearm that accepts a standard STANAG-style magazine and is chambered in 5.56x45mm NATO or .223 Remington. It uses a standard AR-15 magazine interface, so it should drop right in. Always verify fit with your specific firearm before heading to the range.

Is this magazine legal to purchase and own in California?

Yes. This is a California-compliant magazine blocked to 10 rounds, making it legal for purchase and ownership in California under the state's high-capacity magazine restrictions. It features a full 100-round drum body but is permanently limited to 10-round capacity, meeting current California DOJ guidelines for magazine capacity limits.
