Is there any way to get a better idea of around when this rifle was built? Also as to the stamping on the barrel 'C MP' I have found several places online that say that Busmaster at one time got barrels from Colt but there are also places online that say this never happened. Any way what I was told was that when Remington purchased Bushmaster they sealed. Bushmaster discontinued production of the M17S in 2005. The finish is in good shape but it looks like there wasn't a whole lot of prep time spent before the finish was applied. Bushmaster Firearms International, LLC, based in Carson City, Nevada, United States, is an American manufacturer and distributor of firearms.The company's product line revolves around semi-automatic pistol and rifle variants of the M4/AR-15 design.

USA.' The barrel is stamped 'C MP 5.56 NATO 1/7 HBAR' It is a fixed carry handle A2, the forward assist is foot shaped. All they can say for sure is that it was built before 2001. I have emailed Bushmaster and they said they cant help me since it was built at their old facility and they had to turn all the records over to the ATF when they relocated. I recently picked up a minty Bushmaster A2 HABR rifle from a member here that didnt have many details on the rifle.
