Exclusive: Full MSR Firepower: Check Out The Mag|Coupler

For Modern Sporting Rifles, This Accessory May Be The Smartest Investment

By Dave Workman

People who own semi-automatic modern sporting rifles (MSRs) built on the AR or AK platform are always looking for some new accessory to trick out their guns, whether it’s a different sight, laser or flashlight — something to set it apart from the herd.

I’ve always been intrigued by the simple things, because in my experience simple is best and least likely to let you down at the worst moment. Sometime back, I reviewed a little snap-on tab that fits on the dust cover of an AR-type rifle to protect the receiver finish, and now comes another little gadget so simple it makes my subconscious scream, “Why didn’t you think of that?”

Enter the Mag Coupler from RJK Ventures LLC, a little outfit headquartered in Aliso Viejo, Calif. Trust me on this, the Mag Coupler is a product that literally lives up to its name, because it does exactly what it’s designed to do.
