Review on CTA Tools 1120 Small Cylinder by Punk Espinoza

I used this on a project which I'm sure the engineers didn't have in mind when developing this tool. Bought because I bought an AR-15 rifle barrel that was milled to .750 in the gas port and a low profile gas block that happened to have a .749 bore due to parking. It is necessary to remove about 0.0015 from inside the gas block. The stone "wings" are adjustable, but they seem to put more pressure on the base than evenly along the length. Just make sure you hone along the barrel (both ends if possible) to fix this problem. I also don't know how long this tool will last with repeated use, but it solved my problem. For the price, if this is the tool you need to solve one problem at a time, it will meet your expectations for a low price. This is the added report after 7 days. done before and the plastic inner rod broke and the tool is unusable. Again, if your project is small, this might work well for a limited time, but it's not the kind of tool you can count on hanging from a tool board. .
