Just thought someone might be interested...
received this via email. Not sure I see what the big deal is, isn't a piston upper?
Yup.. it's a piston upper.
I just picked up one of these rifles about a month ago, ( haven't had the chance to get it to the range yet ) and I'm pretty impressed with it, ( so far )
The upper by itself is nice, but I actually like the innovations in the lower, much more.
