Torque barrel removal tool
Excellent tool. Locked it down in my vice & worked super great holding my barrel rock solid in place so I could get that stubborn free float barrel nut to break free, sheeesh. Best part about using this tool is I don’t risk warping or otherwise damaging my receiver going into gorilla mode on that stinking barrel nut!

Receiver / barrel saver
Works flawlessly. Some nut attached a flash suppressor to an AR barrel without a washer or a lock nut, using locktite red. Heat plus 80ft/lbs broke it lose. No way I could have done it without this tool.

Good tool for barrel exchange.
I used this tool to change the barrel on my AR rifle. The tool makes sure you are not putting any stress on the upper receiver, all the force goes through the tool into the barrel extension.

what Ineeded
Invaluable tool for those really tight barrel nuts to remove and then much better torque control being applied in line with the barrel for reinstallation. No more worries that too much force is being borne by the upper casting during remove and replace operations.
