Otis Technology AR Lock Block
$123.45
The Otis Technology Pro+ AR-15 Lock Block is designed to make the removal and installation of barrels and even hand guards quicker, while also allowing you to tackle stuck barrel nuts with ease. 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, itll 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.

This is a simple solution to firmly holding your barrel/upper in place while adding or removing parts; hand guards, muzzle devices, barrel nuts, etc. The included bushing ensures your receiver is held steady and, though it needs a bit of coaxing to remove from the upper, is not difficult to remove.

Great item to have if you assemble ar platform’s. The brass bushing helps to prevent damaging your upper receiver and takes the slop out when using the lock block.

Great quality and easy to use. Good way to make sure your barrel is installed correctly or the upper is centered correctly for the barrel. Works great for what it’s actually made for. Highly recommend

Was having trouble installing my muzzle device and keep from twisting my Adams Arms piston gas block out of alignment. This lock block holds the barrel solid, not the upper receiver. You can really get your muzzle brake/flash hider super tight without fear of putting undo stress on the upper or messing up barrel alignment at the upper.
