Promag
Building or maintaining an AR-10 gets a lot easier with a dedicated lower receiver action block. The ProMag Armorer's AR-10 Lower Receiver Action Block is a simple, indispensable gunsmithing tool that clamps into your workbench vise and securely holds your lower receiver while you install parts or perform detailed cleaning and maintenance. Whether you're assembling your first .308 rifle or working through a collection, this block frees up both your hands for precision work — a luxury when you're fitting trigger groups, installing buffer tubes, or doing thorough post-range cleaning.
Made from injection-molded polymer and manufactured in the USA, this action block is built to take the daily wear of the armorer's bench. The design accommodates popular AR-10 lower receivers, including Armalite, DPMS, Remington, SR-25, and other standard variants. Its straightforward clamping system means setup is quick and tear-down even quicker — no special vise hardware needed beyond the bench vise you probably already have.
If you're serious about keeping your rifles tuned or getting builds done right, a good vise block pays for itself in time saved and frustration avoided. This one handles the job without fuss.
