Featuring a unique coupling mechanism integral to the floor plate, couple two magazines end-to-end in 4 unique configurations in seconds, allowing faster reloads so you can RETURN MORE FIREĀ® Designed and manufactured in house at our state of the art factory in Canada, we know what it takes to withstand frigid temperatures, rough handling and competition use. The transparent bodies allow quick visual indication of how many rounds you have left, or the type of rounds, which is particularly useful for running 300 blackout. The integral coupling floor plate allows you to couple the magazines end-to-end in either a curved or straight configuration, from there you decide if you want your cartridges facing forward forward, or forward reverse. If you ever change your mind about a configuration, change it in seconds, without extra parts or special tools. Or heck, uncouple the mags and take advantage of lowprofile mags to shoot prone, on a bench or hunt in the woods. Features: Integral floor plates 4 different configurations Two 10 round compliant magazines Translucent polymer No tools required Mags can be used when separated Compatible with 300 blackout cartridges
