I would like to know what type of Krieger barrels you guys have. I just called them to talk about making me a barrel. Here is what I want, I want an 18" barrel, with a .875 gas block and .850 muzzle. They said the DO NOT cut any AR-10 barrels under 20", and they do not make any custom grinds on the journals. Only the M110 service barrels have the .875 gas block and .850 journal. They only cut a .937 gas block and .900 OR .812 muzzle. It says all over their site, UP TO 26", I figured that mean they make them short too. Am I just wrong, or does Krieger make shorter .308 AR barrels?
