| Am I right the only two parts that are caliber specific is the upper and the barrel? Want some suggestions on both of these I am going to build a 6.8mm. |

Then the page count to me is UPPER Receiver (M4 feedramp or file/grind it yourself), M4 Barrel Extension, Barrel (FSB or gas block and flash hider), Bolt, and Magazine - Mission Complete. While it is stated in many, many posts that the M4 feedramps are not required...It seems to help the feed jam problems of the 6.8mm.
