Brn-4 Barrel Nut Wrench

The Correct Tool for Safe Installation/Removal of Barrel Nuts on H&K Rifles as well as BRN-4 Rifles! This wrench is a necessary tool if you need to assemble one (or several) of our BRN-4 setups. Actually this tool is a must-have item for anybody who works on H&K Rifles, or Brownells very own BRN-4. When installing or removing the barrel, this wrench precisely engages the slots in the barrel nut, ensuring all the torquing force is evenly applied without the wrench slipping off and damaging the barrel or nut. Just slide the tool over the barrel nut, hand tighten the hex nuts on the tool, and start tightening/loosening the barrel nut using a standard A 1/2" torque wrenc Mfg: Brownells
