Found this piece while doing a "budget build" and expected something that was basically crap (after all, comparable products on the shelf at the gun shop go for about 140 to 220 dollars, how good can it be for 40 bucks?)
The answer is "Very."
Apart from being ever so slightly heavier, you can't tell the difference against high-end rail-style hand guards. It even comes with the barrel nut. Easily shaving 100 dollars or more off of the total cost of my AR.
As I said, this was for my budget build, built with an eye toward a low bottom line (I followed auctions, watched for daily deals on dozens of online AR sites for every piece of the build) and I can say with some certainty that there is not a better priced hand guard of this style anywhere online or otherwise.
