Rimfire Build Block


Patent Pending

The BoreBuddy Rimfire Build Block is the ultimate bench companion for AR22 builders and owners.  It holds the upper securely for assembly, maintenance, and repair.  Flip the block over and it’ll hold the lower securely by inserting the block into the magwell.

We’ve been using this tool internally to streamline our upper building process for nearly a year and now are offering it to our customers!  You’ll wonder how you used to get before the Rimfire Build Block using clamshell style mounts or clamping the upper between wood blocks!

Includes a quick release pin for the front takedown pin support.
