Fab Defense OMC Magazine Coupler Features The FAB Defense OMC couples two 10-round Ultimag magazines side by side giving an AR platform shooter immediate access to a second loaded magazine the instant the first runs dry. Because the coupler is an external accessory rather than a replacement floor plate each magazine keeps its factory function and can still be loaded unloaded and used on its own when separated from the coupler. The design maintains the 10 round capacity limitation on each magazine making it a straightforward option for shooters in capacity-restricted jurisdictions who still want faster reloads. Its highly ergonomic shape is built to be gripped naturally during a magazine change so the transition from empty to full magazine stays smooth under pressure. Built from durable high grade polymer the OMC stands up to repeated mounting and dismounting without cracking or wearing out and it adds minimal bulk to a loaded magazine. At 3.11 inches long 8.07 inches tall 1.18 inches wide and 0.48 pounds the coupler is compact enough to carry without becoming an encumbrance on a rifle or in a range bag. It is compatible with M16 M4 and AR15 variant magazines covering the most common rifles built on the AR platform. The FAB Defense OMC is for sale at GrabAGun for shooters who want to shave seconds off a reload without investing in higher capacity magazines.
