I don't know where you got that about steel casing ammo being a myth, but it WILL in fact screw your AR up resulting in an EXTENSIVE chamber/bore cleaning to get it right again. What happens is when you get "happy" shooting your AR, and the lacquer melts, it will form an thick film when it cools back down and will solidify. The next time you attempt to shoot it, the LEAST that will happen is ammo getting stuck in chamber or not chambering all the way. PLEASE don't mislead other people which may result in firearm damage or injury based on uninformed opinion. And YES the company that bought Remington is in fact the same company that owns Bushmaster. The Remington R-15 and it's bigger brother are in fact Bushmasters.

If you're looking for a diff cal look into the .50 Beowolf, or maybe the .458 SOCOM, both available at Rock River Arms(after a lengthy back order). Otherwise I'd go the .308 route. Rumor has it the the new Remington .308 (R-25?)is actually a Bushmaster. Btw, Del-ton offers all their uppers in 5.56. If it were me I'd only buy a 5.56 as it'll handle all the available loads in .223 or 5.56 where as a .223 upper may have trouble with hot 5.56 loads. Also, don't pay any mind to the "steel casings are evil" myth.
