I have a McMillan MBR bedded for a RBLP viper action by S&S precision. S&S also put vents in the forearm. It can be made to fit a Panda, Panda f class and one or more other actions with no trouble. It has been cleared with auto paint and looks good. I got this off of here about a month ago to put a panda f class action in but after I got it McMillan was just about done with the one I ordered inleted for my action. So being all my actions are panda f class I don't want to mess up a perfect bedding job. So this is for sale $500 shipped.
