MTNBoomer,
I have one of those, but it's 18" and rifle gas. They are heavier then you would expect, but shoot great. I've had no issues with mine. For my SHTF rifle, I went with their 16" midlength gas in the Government profile.
They also make a 18" ultralight profile as well. I've built one of those in rifle gas. Another shooter. Unfortinately they don't make the ultralight in 16".
If I was building today, and had my choice of parts, this is where I'd look:
