The AT3 SPEAR™ is our best, most secure handguard. Simple to install, lightweight, and easy on the wallet.

The slim free-float design enhances accuracy while minimizing the weight of your rifle. M-LOK attachment slots and included rail section provide unlimited options for accessorizing your build. And with an available Billet Upper to perfectly match the slim profile, the SPEAR (Slim Profile Ergonomic Adjustable Rail) creates a unique look to set your rifle apart.

With 9″, 12”, or 15” lengths available, the SPEAR handguard is ideal for customizing your next AR-15 build or upgrading an existing rifle. If you’re starting from a stock rifle, make sure you purchase a Low Profile Gas Block with the handguard.

Frequently Asked Questions:

Will this fit my AR-15?

The SPEAR is specially designed for use with our matching Billet Upper Receiver as well as the majority of mil-spec AR-15’s on the market. In most instances, it will also require the use of a low-profile gas block that fits underneath the rail.

This product will not work with non-milspec upper receivers like the Bushmaster Carbon due to the non-standard barrel threads, and it is not compatible with most piston kits as they won’t fit under the handguard. Additionally, this rail will not work with gas blocks that are irregularly shaped or exceed 1.3 inches in height or width.

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 – most setups will require a low profile gas block.

For tools – we recommend:

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)
