If you're assembling or performing maintenance on your rifle, you know that they aren't designed for traditional tools to be used and that the right tool can make a difficult job simple. The BOUNDARY 41877 Gunsmith Combo Wrench brings many of those tools together in one multi-tool style 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-inch 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-inch drive cutout to allow you to use a torque wrench when tightening barrel nuts. With an all-in-one design and easily cleaned powder-coating, this is one tool you need to add to your arsenal!
