Sadly I'll be returning it. On inspection it looked decent enough. Your AR15 free float handguards are good to go though.

Some suggestions for a gen 2:
-Include some instructions, torque specs, and hardware thread pitches/sizes.
-Top rail sits too high. Putting anything on it will block irons. There is no reason not to lower it slightly. If it's an issue just have cut outs for the gas tube hand-guard retainers.
-Mounting hardware is on the cheap side. I also believe mounting an optic on the top rail won't hold zero with such small screws. There isn't much metal for them to thread into.
-Make the clamping part of the rail sit more flush with the rail itself.
-Better anodizing
If you have to go with a Chinese made handguard. I'd just get a Zenitco Copy. Those are pretty good quality for what they are.
