AR-10/AR-15 Free-Float Armourer's Wrench

Not sure which wrench you need? Check out our handy comparison chart.

This specialized tool is designed to perform important screwing jobs when working on your AR-15 or AR-10/AR-308 (full list at the bottom of this page). Tailored for folks who only work with free-float handguards, it saves on size and weight by not having the rippled wrench for basic USGI barrel nuts.

There is a square hole for a 1/2" torque wrench (not included) to get the perfect amount of torque on your barrel nut (though many people use a calibrated wrist).

We also sell barrel nut grease to prevent thread seizing.

Specs:

  • Steel
  • Can open a lobster and/or a mobster like a boss but this is off-label usage
  • Weight: 355g
