Tapco Mag Coupler 5.56x45mm Fits AR-15 Black Aluminum

The Tapco Mag Coupler is purpose-built to lock two AR-15 magazines together as a single unit, effectively doubling your on-gun round count for 5.56x45mm without forcing a manual reload in the middle of a drill or stage. It's a simple, low-profile accessory for range days, carbine classes, and defensive setups where carrying extra ammunition in parallel keeps the rifle topped off and ready.

Constructed from durable 6061 machined aluminum with a black finish, the TAP22091 is built to handle hard use while keeping added weight to a minimum. The coupler clamps two AR-15 pattern magazines side-by-side so they stay aligned and feed reliably, and it is compatible with most standard 5.56x45mm AR-15 magazines on the market.

Installation is quick and tool-light: slide the coupler over the two magazines and tighten to lock them in place. When it's time to swap, the magazines release cleanly so you can drop a fresh mag into your rifle without delay.
