Chris Bartocci (Small Arms Solutions, author of Black Rifle 2) did a good review of the weapon here:
I still believe that a gas piston AR is a solution in search of a problem but as gas pistons go this one seems very well executed. It was developed in the UAE but is manufactured in the USA by Wilcox Industries in New Hampshire.
They are priced around $1650.
If any LFer has trigger time with one please chime in.
