I have a Black Hole Weaponry 18 " 6x45 1x10 SS P3 Mid length gas port if that would be of interest to you.
I bought it from a member on Predator Masters forum so I don't know the number of rounds fired. I never used it but the rifling looks great.
It does have a couple of dimples from the gas block from the previous owner, other than that it's in great shape.
I don't have enough posts or whatever else it takes to PM you here. I am on Accurate Shooters Forum and Long Range Hunting Forum under the same name if that helps.
