About the Range Tool M-LOK Handguard

Lean, functional, and affordable.  That’s the philosophy behind this US-made free float M-LOK handguard from Range Tool.  A high value AR-15 handguard that has all the features for building the gun you want, with none of the fat to cut down on cost.  For the builder on a budget or a first-time upgrader, this is a great place to start on building a better, lighter, more accurate rifle.

In spite of the cost, this handguard is feature rich.  A sturdy steel barrel nut ensures rigid lockup with your upper receiver, with anti-rotation tabs for extra security.  The included screws and square nuts are steel as well, perfect for getting the correct torque value when installing, without fear of stripping the threads.

Seven sides of M-LOK slots spanning nearly the entire 15 inch length ensure you’ll have all the room for accessories like lights, lasers, and bipods that you’ll need.  A full-length picatinny top rail also serves as a perfect place for backup sights and pressure pads for lights.

If you’re looking for all the features that the big boys have for their handguards, this high value AR-15 handguard is a perfect upgrade for your next project.

  • Once the handguard is secure, choose whatever M-LOK accessories you like to make it your own
  • Check out the video below for Installing our AT3 SPEAR handguard – the Range Tool version isn’t much different!

Installation Guidelines

  • Use a lithium moly grease or something similar on the receiver threads and barrel nut
  • Torque the barrel nut to 30-60 ft-lbs using a torque wrench
  • Align the top of the handguard with the picatinny rails on your upper receiver
  • When installing the nuts and screws, torque the screws to 30 inch-lbs.  Use blue threadlocker if you’ve got it!

Note: most rifle setups will require the use of a low profile gas block that sits under the handguard.

Frequently Asked Questions:

Will this fit my AR-15?

The Range Tool handguard is designed for use with standard forged (AKA mil-spec) upper receivers.  When you buy this kit, you’re guaranteed to have a good fit for upper to handguard.

What tools and additional parts are required?

For parts – almost every setup will require a low profile gas block for your barrel.

For tools – we recommend:

  • 30mm Crow’s Foot Wrench with 1/2 inch drive for the barrel nut
  • AT3 Barrel Nut Wrench – it will work with the Range Tool barrel nut, but may be a tight fit
  • A vise and non-marring vise block for holding the upper
  • A torque wrench to assure you stay in the AR-15 barrel nut torque range while timing the barrel nut (30-60 ft lbs)

Range Tool 15 Inch M-LOK Handguard with Forged Upper Combo

Good points-low price, anti-rotation tabs, consistent black anodizing, decent machining, steel barrel nut. Disappointed that it only had friction clamp type grip on the barrel nut using two small screws instead of a better lockup mechanism.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. If you encounter any issues, please let us know.

A very good deal

A keyhole upper and m-lock forearm for this price. A hefty steel barrel nut to boot. I am happy!
