The front profile of this handguard is designed to match the look of the Diamondhead T-Brake, so you can build an aesthetically pleasing rifle that is much better to shoot than an AR with stock components. Installation is easy with the included barrel nut that eliminates the possibility of timing issues. Instead of screwing it on to the barrel nut, it simply slides over and is secured by high strength screws to ensure it is flush with your receiver and won’t back off over time.

Ratings & Reviews
Loved it until I installed it
by Kirby -
This handguard is super slim, well made, has anti-rotation tabs and feels great in hand. The top of the rail is 15" but the bottom is about 16 3/8" which is too long to use on my 16" barrel. A properly torqued barrel nut on my Aero Precision upper receiver places the barrel nut too close to the upper receiver causing the handguard to cant down about 16th inch at the front of the handguard. Barrel nut spacers (not included) will fix the problem. Also the inside of the handguard is touching my Odin Works adjustable gas block so I will need to purchase a lower profile gas block. I would have given it 5 stars if the package included barrel nut spacers, if the description said that the length was 16 3/8" instead of 15" and if the description did not say "Installation is easy with the included barrel nut that eliminates the possibility of timing issues." I obviously have timing issues.
Handguard is longer than 15"

Nice quality looking handguard. Comfortable in the hands. Knocked 1 star for the fitment reasons listed below:
<br>It is not a 15" handguard. The top rail measures 15 1/4" and the bottom of the handguard measures 16 3/8" (this will be hit by vented gas from a muzzle brake or flash hider on a 16" barrel) I would suggest having a minimum barrel length of 18" with this handguard.
<br>Use the 13.5" with a 16" barrel to avoid vented gas from the barrel hitting the handguard as the handguard is longer than a 16" barrel.
<br>Also should note that it has 2 tabs on the back that wrap around the top section of a mil-spec forged upper receiver. Those tabs will interfere with proper fitment on some billet upper receivers. However: you can fix by cutting/grinding the tabs off and touching it up with black paint.
<br>As usual: Primary Arms is a great trustworthy business, ships fast, and their customer service is excellent!
