I have bought a few barrels from x-caliber and this is an email they just sent out
[FONT="]6mmAR/243LBC-[/FONT][FONT="] This incredibly accurate cartridge is created by necking down the 6.5 Grendel.It is designed to use the High BC 6mm bullets in the AR15 platform. Our friendChad@ iv8888 is working with this cartridge in one of our barrels and theinitial reports are stunning. During testing he shot a group measuring1.90"(.30 MOA) at 611 yards with one of our barrels on an AR15 platform.The 6mm AR will be a solid contender for the most useful AR15 cartridge foryears to come.[/FONT]
