JE Machine Tech AR15/M16/M4 Vice Block Combo Features The JE Machine Tech AR15/M16/M4 Vice Block Combo includes both an upper and a lower receiver vice block giving builders and armorers a complete solution for securing an AR-platform rifle during maintenance. Each block is molded from heavy-duty polymer that clamps safely around the receiver without marring the finish or stressing the material. The combo is built specifically for the AR-M16 platform so the fit is precise and the receiver stays stable during pin removal cleaning or parts installation. This kind of secure clamping is essential for any task that requires two free hands and a rifle that will not shift. Because the blocks are solvent resistant they hold up to the cleaning chemicals and lubricants that are a normal part of AR maintenance without degrading over time. The matte black finish keeps the set looking clean on a bench while resisting scuffs from repeated use. Compact packaging makes the combo easy to store in a range bag or tool box between projects. For anyone who regularly works on AR15 M16 or M4 rifles the JE Machine Tech Vice Block Combo is available for sale at GrabAGun.
