AR22/AR9 Build Block

Patent Pending

The BoreBuddy Build Block is the ultimate bench companion for AR22 and PCC AR 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.

Compatible uppers:

BoreBuddy pattern 22LR/21 Sharp

Blowback AR PCC (9mm, 40, 45, etc)
