Well, since you said please ...
I had the SU 16C and I loved it. It was pretty accurate and the portability made it a great camping carbine. The fact that it takes AR magazines is a huge plus too.
My wife and my buddy's girlfriend and two teenage daughters shot it too and they all shot well and accurately with it at 50yds. None of them complained about the ergonomics or the recoil. The bipod makes for nice steady aiming.
It is not
a tactical rifle and shouldn't be tricked out like one. It is what it is,
a practical, portable and handy carbine that can do what it is designed to do well.
