Most Helpful Positive Review Excellent Forend. Tricky Install
This is the best and most solid feeling handguard I have used and/or installed. This thing feels perfect in your hands: the diameter is perfect, the finish is smooth durable flat back, and it has a soft feel in your hands. 5 stars for the forend, -1 star for the install, but that is inherent in the design. I very much appreciate the 45 degree MLok slots all around. This is the perfect location to mount a Scout Light with an inline mount such as from Arisaka or Impact Weapon Components (IWC). I have another high-end brand forend that has almost MLok slots at 45 degrees, but they are not u...

Quality product but a pain to install

by Theoboom, Verified Owner from MD, United States Written on April 1, 2022
So this handguard incorporates the barrel nut into its design, this means that the handgaurd must be installed prior to the gas block as there is not enough clearance as you thread the barrel on. If your installing a gas block that requires set screws you’ll need to access those through the mlok cutouts from the bottom, or in my case by drilling a small hole to hit the hex bit thought. In the end it worked, looks great. 10/10 id do it again

Diameter is just right

by Brandon, Verified Owner from TX, United States Written on February 29, 2020
I got this for a 9mm pistol build. I had seen reviews here and online (forums, etc) that claimed the total length is 8.75 instead of 8.5. This is not true. It’s exactly 8.5”. The shims add a TINY bit but not much. The size is perfect and feels good in the hand but the texture is less than desirable. I was hoping it would have a smooth anodizing but it’s rough and leaves an ashy white appearance all over...and my wife makes me put balm on my hands so they’re not the driest hands ever. I’m hoping it will smooth out over time otherwise I’ll be paying for cerakote. Overall I like it for this build but installation and texture have talked me out of using it for a new duty upper for work.
