I just built a C7A2 ish build along these lines.
I liked the Canadian C7A2 but also like the M16A2 modded with CAR buttstock. I have a couple pics saved of a guy in Desert Storm chocolate chip camo with an A2 with collapsible CAR stock.
I got a C7A2 lower from Bad Attitude Dept and was going to build that first but real Diemaco parts are hard to come by, and pricey whem you do find them.
I ended up building a hybrid to try out the general pattern. Not a clone of anything, but I like the layout.
BA C7A2 lower, C7 upper, A2 rear peep and square fron post. 4 position buffer and CAR stock, A2 grip and handguards. 20 inch 1-7 pencil barrel with A2 flash hider.
