Just recently purchased the rail. Right out of the box this thing looks and feels great. Definitely a well made rail system, now on to the pros and cons.
Can run your bare hand over the rail without getting cut
No wobble once installed correctly
Looks amazing, especially when replacing the stock polymer hand guards on a VFC M16A3.
Anodizing looks great but scratches very easily. Installed a bipod, clamped it on the rail then went to take it off. Just from clamping it on without siding it at all, it had already started showing the silver of the aluminum.
No gas tube pass through on the barrel nut, so my front site post cannot be installed with the gas tube to help stabilize the barrel without cutting said gas tube.
Literally requires a vice to tighten barrel nut down enough to get it to line up (not really a con if you have a vice)
