I have 5,000 lb. D-rings thru-bolted to the outside of the trunk, with two of the extra-hardened master locks, front and back on each chain. The orange peg holders are bolted through to hold the rifle, while the D-Rings, chain, and locks secure the rifle to the truck.Nice looking rig! I like your Calico Jack valve stem caps.
Tell me more about your AR-15 rack. What secures the chain in the pic? Do you have a combination lock or keyed padlock or something that chains the AR to the trunk?
