The Stand-Alone WarBlocks come by themselves for Do-It-Yourself pinning. While we offer complete pinning services in the WarBlock Barrel Builder to construct your barrel assembly or upper, many customers specifically ask to purchase just the WarBlock itself for pinning on their own. We now offer it here for those of us who believe that unless we built it, we don’t really own

Each stand-alone WarBlock comes with two taper pins, a gas tube roll, pin, and a conical set screw designed to help with holding alignment during drilling, reaming, and pinning.
