Frequently Asked Questions:
Will this fit my AR-15?
This handguard will work with 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.
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 29mm wrench (an 8” crescent wrench will work, or a 29mm box wrench, or 29mm crowfoot wrench with torque wrench)
- A torque wrench can be also be used to assure you stay in the AR-15 barrel nut torque range (30-80 ft lbs). Since this range is quite wide, is torque wrench may not be needed, but is recommended if you're not experience in torquing AR-15 barrel nuts.

The hand guard screws were of poor quality, easily stripped all 3 just trying to tighten. Would not recommend this set because of the hand guard - stock and grip were fine. They are fast shippers..
