The COMPETITION Carbine Wings Set was designed to enlarge the COMPETITION MultiGun Rig capability to carry extra ammunition. The wings attach directly to the velor on the back of the rig. Additionally, the buckles from the rig goes directly to the side webbing loops on the wings to make it even more stable. The wings were designed to fit one carbine magazine each (will fit standard AR / AK magazine). Antislip interior prevents the mag from falling out.
