XTECH XTT110-BLK-SPEEDMAG SPEEDMAG AR15 30RD

The magazine allows you to pull the collar down as you drop the ammunition into the magazine. This makes it possible to drop several rounds in at a time and load magazines in a fraction of the time with far less effort. The Speedmag works in all Mil-Spec AR-15 lower receivers and will accept any ammunition that fits in regular mil-spec magazines like .223 Remington, 5.56 NATO, and .300 AAC Blackout.
