Yea kinda what Marcus said, Magpul sold it to Bushmaster and they changed the name to Adaptive Combat Rifle (ACR) and there is the odd little change (most notable using the RIS handguard more then the magpul one) however, it is the same basic rifle and all the origional Mgapul ideas are still in there (i.e abidextrous controls, quick change barrel, massive adaptiveness)
oh and when you hear people call it the Remington ACR basically Bushmaster told its sister company, Remington, to make the military ones now while Bushmaster made the civilian ones. The ACR design is still technically Bushmasters as Remington didn't change anything, however, it is still a Magpul rifle.
EDIT: Marcus, I'm expecting you to re-do the camo with A-TACS
