Sleek US-made Handguard for “Spartan” Builds

The Spartan handguard represents the bare essentials for the modern AR-15 – a free-float M-LOK handguard that improves modularity and accuracy on a budget.  The Spartan handguard from Range Tool gives you a full-length top rail, with M-LOK slots at the 3, 6, and 9 o’clock positions for accessories.  Lights, lasers, grips, and bipods, whatever you like, you can mount on this handguard.

In spite of the cost, this handguard is feature rich.  A sturdy steel barrel nut ensures rigid lockup with your upper receiver of choice.  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.

This handguard gives you a great way to improve an off-the-shelf rifle, or finish off a high-value build with a handguard that works.  The 12 inch length works great for a standard AR-15 with a 16 inch barrel, giving you plenty of real estate for grip, without excess material or weight near the muzzle.

Ounce for Ounce Value

  • Free-floating your handguard will improve accuracy .5″ to .75″ MOA compared to drop-in handguards
  • The slim profile and smooth finish makes the rail easy to grip for any shooter
  • 6061-T6 aluminum construction retains light weight, with a steel barrel nut for rigidity
  • 3 sides of M-LOK for your favorite accessories, plus a full length picatinny top rail
  • Hard coat anodized to protect against wear and tear at the range, and in the field
  • Proudly made in the USA on the Minnesota Iron Range!

Simple Installation

  • The Range Tool Handguard installs in just a few steps on the upper receiver, with minimal tools required
  • A 30mm Crow’s Foot Wrench works best for the barrel nut
  • Great for upgrading a stock rifle, or starting a new upper build on a budget
  • 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 process 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 Spartan handguard is designed for use with any upper receiver with standard barrel nut threads.  Since this handguard doesn’t have anti-rotation tabs, pretty much any aluminum receiver you can find will work with the Spartan handguard.

This handguard will not work with non-standard receivers like the Bushmaster Carbon due to the the difference in barrel nut threads.  Most gas piston kits will also not work due to the slim inner dimensions of the handguard.  This handguard does not fit AR-10s, and cannot be adapted for such.

We’re always glad to verify the fit for your rifle, just contact us!  And if it doesn’t fit, we are glad to return it for you. And if you’re new to AR-15, we recommend watching a couple of the videos on our installation video page to understand how the process works.

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)

Not like the last spartan I purchased

Purchased 1 range tool spartan a couple months ago and loved it.. Purchased another one and I'm very disappointed.. it doesn't sit square with the barrel. I really liked the design and how good first Purchase looks so was very surprised with the second one
