CAA MCD16N Magazine Coupler - Fits AR-15/M4 Polymer Magazines

Cut your reload time in half by keeping a fresh mag locked to the one in the gun.  The CAA MCD16N is a two-piece, reinforced-polymer coupler that clamps two 30-round .223/5.56 magazines together at a slight offset so the spare sits low enough to clear the ejection port.  A captive power-spring pushes the magazine bodies outward as you tighten the three captive cross-bolts, giving a rock-solid grip without crushing polymer feed-lips.  Contoured finger grooves and a wide gap make the bundle easy to index, while the open design still lets you read CAA’s MAG17 window or PMAG round counts at a glance.  Despite its toughness, the coupler weighs only ≈ 60 g / 2.1 oz and adds just 2.5" of width, so balance stays neutral and the rifle slides cleanly from a rack or bag.  Built in Israel.
