The Breakthrough Clean Technologies Lower Vise Block, AR-15 (brand part no. BTAR15LVB), gives builders and cleaners a stable, secure way to work on an AR-15 lower receiver. The block inserts into the magwell and locks in place using the receiver’s own magazine catch, creating a snug fit without extra hardware. From there, the block clamps into any bench vise for hands-free stability during cleaning, detailing, or light gunsmithing. An integrated hammer stop tool protects the receiver from damage during dry firing, and the included Pivot Lock accessory gives you quick access to the barrel and chamber without breaking down the whole setup.
