Well looking at their site, unimpressive specs vs. price. Compare them to PSA.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.

I used them many years ago when ther weren't a lot of choices around. I have no complaints from th estuff I got back then. There are more choices of places that offer higher quality parts in the same price range. But, of course, they are not secrets, so alot of those places are getting tapped out with the panic.
