Ratings & Reviews
Great tool Great Price, could use some simple improvements

Great tool. Like others have said, it could have benefited from the flat sides similar to the Geissele. I used a breaker bar in a vise with notches and it worked just fine. I will likely tig weld a piece of square stock in there when I have time, but I knew I could get it to work as it was. It held from rotating just fine but by the time you throw an upper, a 5lb barrel and a 65ft lb torque on er she gets a little squirrly from tipping.
<br>The tool gives you about 3" out the bottom / back side of the upper to secure, so plenty of ways to get creative.
