AR15 / M16 Wrench Combo Tool
The NcStar AR15/M16 Wrench Combo Tool is a full armorer's wrench that consolidates every key wrench profile for the AR platform into one steel-bodied tool. It handles barrel nut installation and removal, both old- and new-style castle nuts on collapsible buffer tubes, A1 and A2 flash hider timing, and includes a 1/2" square drive for torque-wrench use plus a flat-blade screwdriver tip. The black powder-coated steel body holds up to repeated bench work and gives you the leverage needed to break loose factory-torqued hardware. A solid choice for home armorers, builders, and anyone running an AR-15, M4, or M16 variant who wants one wrench that does it all.

Solid budget wrenchPicked this up to finish a lower build I had sitting around. Made of steel it feels hefty in the hand which I appreciate. Got the barrel nut tightened down no problem and the castle nut went on smooth using the three-point wrench end. Just a heads up tho - I saw some reviews saying the teeth can break if you really crank on it with a torque wrench. I stopped at about 35 ft-lbs and used some blue loctite, been solid ever since. For the price point (way less than the Magpul or Brownells options), this gets the job done for your average home builder. The flash hider slots worked fine on my A2 birdcage too.
Price can't be beat compared to Magpul

Very handyGood tool overall, works well for what it is intended to do, seems to be well made, its steel so it should last. A must have if you assemble and disassemble your rifle.

good to have!If nothing else its worth its weight in steel. Lets just say it won't be making out in the field as a lite ar multi tool. It not a precision tool or anything like that, but it will do a lot of the major assembly and disassembly of your ar. It is worth having around for sure!
