Frequently Asked Questions:

Will this fit my AR-15?

At3 tactical spear mlok free float handguard forged upper anti rotation

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)
