Internal Action Wrenches

While not as powerful as an external wrench for cracking factory barrels loose, An internal action wrench is particularly beneficial on switch barrel setups where a barrel can be swapped out without removing the optics or stock.

Machined from 17-4 Stainless; my Internal wrenches have long drive flats for maximum surface area contact on the receiver’s raceway to help prevent damage to the receiver.
