| I'm tinkering around with some aluminum and copper heat sink prototypes and I'm trying to support most of the common IAR/LSW .980 hbars. A few guys on IG plan on running the KAK dedicated L6 barrel but none of them have one on hand. Anyone here have one and mind giving me the barrel OD from the extension to the gas block journal? I might pick one up for dimensioning alone, I'm surprised how many ".980" barrels are tapered or .010-.020 under. |
