The TacFire Upper/Lower Vise Block (brand part no. TL021) gives AR-15 owners a matched pair of polymer vise blocks for both the upper and lower receiver, covering the full range of maintenance, repair, and assembly tasks on the bench. Each block seats into the magazine well from either the top or bottom and holds the receiver steady in a vise without marring the finish. Whether you’re pinning a barrel nut on the upper or installing internals on the lower, this set keeps both halves of the rifle secure and protected throughout the job.
