| has anyone used one of the Model 1 sales 300 blk barrels yet? How are they? I was looking around at my options. I was looking at CMMG but their barrels have f marked sight bases and I am using an A2 Upper. Model 1 uses an A2 FSB. |

supposedly the chambers are tight. this is what the guy who helped develop the cartridge has been saying on some of the supressor forums. if you get the barrel, it will need to have its chamber reamed.
also, the gas port isnt supposed to be ideal and no one knows if the threads are concentric. |
