Diameter is just right - Knight's Armament URX 4 M-Lok Forend Kit

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.
