Product Description

If you've worked on your AR-15 with it simply laid out on the bench, you know how much of a pain that can be! Our precision machined, double-sided AR-15 armorer block is loaded with features for AR gunsmithing work. Rock steady and ready to make any work you do on your AR more of a breeze. This is an absolutely indispensable piece of gear for any armorer or hobbyist armorer with an AR-15.  Please note when holding an upper with this product, do not torque barrels past mil-spec 30 ft-lbs or you can damage the firearm.  Use our modular block system for barrels.  This product is perfect for brakes, suppressors, scope mounting, etc.

It is virtually indestructible and resistant to all oils and solvents. Our precision machining on this block equals tighter tolerances and a more solid block. Most other blocks are injection molded which can give you tight tolerances, but not necessarily a solid block. Precision machining allows us to cut this block from a solid piece of high density polyethylene (HDPE is the stuff cutting boards are made of - tough!)
