Great Tool! by Qwest, June 8, 2018
Before I bought this I used a AR Vise Block. I did not believe this was worth the price but when I started working on what I consider to be my last AR build I bought this tool. I bought a Battle Arms Development stripped upper and lower receiver whic...

Another great tool for my workbench by ARHobbyist78, January 31, 2019
What can I say, it's simple and it works. When I want to remove the barrel or muzzle device and don't want to worry about creating stress on the upper receiver, I throw this in the bench vice and crank away. It is a bit pricey for what you actually...
