i am currently soaking it with boretech carbon remover, i shoved a wet patch into the neck and ran carbon remover thru the barrel.
I believe they did but am not sure. So no help there.
The one buddy who got his rifle cured of the problem had a 284 that shot 0.1 moa. It was (and now is again) a lazer! He used CLR, Bore Tech Carbon Remover, JB Bore Paste, many long soaks and lots of brushing. It took him the better part of a week but he got it restored and shooting lights-out again. It bugged him enough that he sold his RL23 and went back to H4831sc though.
