Ok, tis the season for new firearms. Looking for a new rifle for both personal and work use. Got to be 5.56 unless I can get something else approved, I'm really liking the ACR, but considering the SCAR and a number of AR type weapons. Any advice from owners/ users/ former owners etc.. would be greatly appreciated. Pics too. Lately from prices I've seen as far as ACR/SCAR goes, the ACR has the price advantage, being somewhat competitive with Gas piston ar platforms. Also curious as to any experiences with the SIG 556.
