Hello I have a Colt Mk IV series 80 with a compensated Clark barrel. :grin: When I bought the gun from a guy it had some lead build up in the compensator which I cleaned out, but I have noticed that since that first cleaning it has slowly built back up to the point where I had to clean it again the other day. Is this something that is normal or is there something I should be doing differently?
Thanks for any information and advice that you can give me.
Don
