How To Install the Wrenchman LW Handguard

Author Caleb Savant
2 years ago

   Brownells Gun Tech™ Caleb Savant shows us how to install the Brownells Wrenchman Lightweight Handguard for AR-15. The first step is to make sure you have everything in the box: the Wrenchman LW itself with barrel nut, barrel nut wrench, Allen wrench, and the instruction sheet. Start by removing the barrel nut from the handguard using the Allen wrench. Put a little Brownells Action Lube Plus or any similar grease on the barrel extension and insert it into the upper receiver. Slide the barrel nut over the barrel with the notches facing the muzzle, hand-thread it onto the upper, and tighten it with your torque wrench set to 40 ft.-lbs. (Anywhere from 30 to 80 ft.-lbs. will work - the AR-15 is forgiving.) The barrel nut doesn't have to be indexed, so it's easy to install. Now, install the gas block and gas tube. Slide the handguard onto the barrel nut - anti-rotation tabs on the 'guard guarantee you'll get it aligned correctly. Insert the indexing plate into the handguard. Good news - the plate goes in only ONE way. Insert the two locking screws through the bottom rear of the handguard and snug 'em up with the Allen wrench. Your AR-15's new Wrenchman LW handguard is installed!
