Preparing my RUGER PC carbine for Steel Challenge

I am now ready to compete in a local Steel Challenge with the MCARBO internal upgrades. to my RUGER PC chassis carbine.
IMHO I feel all these upgrades are necessary for a carbine that will be subject to the use found in training for and competing in Steel Challenge events. If you want dependability then M
CARBO gives you that.

If you are thinking about competing then get your carbine ready as well as yourself.
