|I used this tool for my AR-15 build everything worked except for my freefloat barrel nut YHM. I know YHM has there own tool for there B/N. Overall, if you build guns or your just starting get this tool... I do like the 1/2 drive adaptor on the tool so you can torque down the parts, ie flashhider, B/N ect ect.
Thanks CTD :-)|
