Works exactly as described. - Precision Reflex DPMS/KAC Barrel Nut Torq Wrench

Used it for mounting my PRI mk12 style barrel nut. Worked perfectly for me. There are little circular marks on opposite sides to help align the barrel nut holes to the gas tube hole. That helped me immensely. I was fortunate enough to be able to align my nut while keeping within torque specs without the need for shims. It’s not expensive for a tool, but sadly will probably only be a one time use for me. I don’t foresee myself building multiple ar10s.
