SIG MPX Mag Coupler

Clamp two SIG MPX magazines together using our simple and durable SIG MPX Mag Coupler.

Insert your mags into the SIG MPX Mag Coupler, tighten the included bolt until the mags no longer shift, and you're ready to shoot. Be sure to avoid overtightening your coupler to prevent warpage and failures. The SIG MPX Mag Coupler includes a bolt and thread, securely holding your magazines in place; our grip tape ensures that your magazines don't shift while in use. Please ensure you select the correct variation of magazine. MPX magazines differ in size whether you have the opaque magazines (pictured) or translucent magazines (not shown). Compatibility Compatible with any carbine or rifle that accepts standard width SIG MPX magazines. Ensure there is 30mm or 1.2 inches of spacing below your mag well for installation.
