This exclusive package from RAP4 is designed to immerse you in mil-sim realism right out of the box⦠and get you ready for â Operation End War, â this fallâ s hottest scenario. RAP4 engineers started with our state-of-the-art T68 Gen6 body, featuring the SplitFire collar which indexes between the included magazine and optional hopper. Then they customized it into a clone of the M4 battle rifle. Featuring a 12â tactical barrel enshrouded in M4 handguards, the marker includes a detachable carry handle with integral rear sight that is ready to accept M4 scope mounts and optical sights⦠or mount them directly to the mil-spec body rail in place of the carry handle. The T68 Gen6 gives you plenty of accessory rails to attach lasers, lights, and other mission-essential gear.
