Like A One-Piece Tool Kit

Handy all-in-one tool handles the tasks necessary to build and maintain your AR-15 or M16. It's a barrel nut wrench, muzzle device wrench, spanner wrench, forearm wrench, flat tip screwdriver, A2 tube remover, receptacle for ½" drive/torque wrench - and a bottle opener. Long handle give plenty of leverage for buttstock and barrel removal/installation, and the ½" drive receptacle allows the use of a torque wrench, so you can get things tightened down correctly. It even has a flat face on one side that can be used as a hammer.
