Held in a standard bench vise, the AR-15 Lock Block locks into the barrel extension, securing it from twisting and minimizing the chance of marring. Give it all the elbow grease your project needs, the AR Lock Block has you covered. The torque is applied to the barrel extension rather than aluminum upper – for a stronger, more secure hold. To accommodate internal receiver differences present in the market, the AR-15 Lock Block is designed with a bronze bushing which allows the tool to work with slightly smaller internal specs. Designed for milspec receivers, the AR-15 Lock Block works on most ARs. Crafted from 1018 steel and finished in a manganese phosphate coating, it’ll stand up to the job and then some. To use, simply lock the tool into a standard bench vise at your designated working angle and slide your upper receiver and barrel onto the AR-15 Lock Block. The tool then engages its locking lugs into in the barrel extension to alleviate the tension on the receiver and placing it on the extension itself.
