thats what I figured. I have that one already. I cant believe I have had it for 2 months now but havent used it. Im embarrassed. But i would love to get my hands on the 556. its so beautiful, although I must say loking at pricing, I'd rather pay american pricing than Canadian for it. 1900 is already hard enough to come up with let alone 2500 for one in canada...if they ever brough them here. too bad Ruger wouldnt change the caliber to a 223 instead.
