well it looks like nearly every barrel i have been looking at is pretty much on BO.
i could probably get a heavy middy from JSE--sometime could be weeks or a couple months-- no chrome lining and it is a heavy---
the barrel i want a LW chrome lined middy is on a long BO--like 9 months to a year.
i have found a m-4 DPMS chrome lined 1in 9 14.5inch
anybody use this barrel? i sure it is a 4140--but with the slow twist rate and chrome lining i am thinking it should last virtually "forever" for my intended use. anybody have any user experience with the DPMS barrels???
