The UTG AR-15/AR-308 Armorer Combo Wrench installs and removes the parts you swap most often on both the AR-15 and AR-308 platforms: a standard A2 flash hider, the delta ring assembly, a rifle-length buffer tube, a carbine buffer tube castle nut, and more.

It is steel with a wear-resistant phosphate finish, and it accepts a 1/2" torque wrench, so you can hit torque specs instead of guessing.

Features:

• UTG Pro super slim free-float barrel nut wrench
• Compatible with 1/2" torque wrenches
• 3/4", 7/8" and 3-prong slots for most muzzle devices and 3-prong flash hiders
• 5/8" slot and flathead screwdriver for rifle-length buffer tubes and fixed A2 stocks
• Carbine buffer tube castle nut and delta ring
• Steel construction, phosphate finish

Check that your barrel nut, muzzle device and castle nut follow standard mil-spec patterns before you use this wrench on them. Support the upper in a vise block when you torque a barrel nut, and stake the castle nut after install.
