I know that some people use this tool, and say that if you break the pins of its becaue you must have put way to much torque on it while putting on the free float tubes. bla bla. Well i broke one last thursday night. So, I figured it was my fault and didnt call dpms. I just ordered another one that night from Bravo Company. I got it in today and used it to torque my barrel to 64 pounds and the pins didnt break but they did bend. Please do yourself a favor and find a more heavy duty tool to use. My first cousin is a machinist and drilled out the pin and replaced it with a new one. He guaranteed me that it would never break. If anyone is interested in a free float tool that is guaranteed to never break let me know. Im going to try to get him to make some and send them out to some people to try out.
