GUNSMITH COMBO WRENCH

This handy tool is made of durable, heat-treated steel so it won't bend or break during use and when torqueing nuts. Featuring a double sided barrel nut wrench that works on both USGI and free float style nuts, a flat-head screwdriver for stock screws, a 0.76" and 0.64" square wrench for installing and removing flash hiders and muzzle brakes, and both a one and three point castle nut wrench for most styles of end plates. There is also a 1/2" drive cutout to allow you to use a torque wrench when tightening barrel nuts.
