Precision machined from 6061-T6 aluminum extrusions then type 3 hard coat anodized, you can be sure that this handguard will withstand an incredible amount of abuse.

very nice product
Over all a very nice product.
USSlim and light
I wanted something other than the standard forged or typical bulky billet upper. THIS IS IT! I paired it with a Foxtrot Mike hybrid lower. Fit and finish is better than I expected. I used a 5.5” barrel under the 7” hand guard option. It looks great!
USNBS Slick Side Upper + Handguard
Very nice color match, the finish is excellent and their fitment couldn’t be better. I’m very pleased with this setup.
USReceiver and handguard combo
The item was great when it finally came after being 5 days late in the mail..... Blaming the USPS for that..... It seems to be well made and colored. I got the FDE color and is well matched to my other items in that color..... I will definitely buy another one soon.... Thanks!
USGreat fit!
The handguard and upper combo is a great deal! Solid construction and i love the cuts on the upper. Also really like the anti-rotation pin to keep everything nice and tight
