The 50 BMG bolt kit contains hardware to hang one target with 2 high strength bolts, 4 washers and 2 locknuts.One kit is required per target, we also recommend a spare. The bolts are high strength but after a few direct hits they will break. High strength bolts will outlast other mounting methods including quick links.Assemble in the following order: bolt, target, chain, washers, lock-nut. Do not fully tighten the lock-nut. Leave room for the chain to move.The target and chain are NOT included, they are shown for demonstration.
