I picked up some of Huang's products planing to put some Airsoft Rifles together to do some "live fire"/"active shooter" style training rifles for LEO work. They are being built to mimic real steel rifles to make training as close to real as possible...Airsoft's cheaper than simunitions.
I thought I'd post some pics and my impressions of the CNC'd handguards that Huang is offering.
The units appear to be all aluminum with the exception of the barrel nuts, the interlock pins and the small parts in the plastic bags. The barrel nut and interlock pins appear to be steel. The gas tube on the Carbine is a tube, while the gas tube on the longer RAS is a solid rod.
The finish appears to be more of a parkarized finish than an anodizing, but Mr. Huang says it's anodized. Either way, it works.
First up is the unmarked Carbine Handguard(6 holes):
Here is the Longest RAS currently offered(12 holes):

I just stumbled across this pic on installing similar two piece railed hand guards:
