Encore,
Well was hoping someone would of answered your post as my info isnt exactly what you asked. First let me say I like RMC products, have also met some of their guys at the trade shows and came off with a positive feeling. I was at their store recently and looked at one of their rifles. I was very impressed and would have bought one then if they had what I was looking for in stock. I want a left handed, flint, .50 cal. Have one on order.
Also of interest is a flyer I received from them when I ordered a CO2 discharger. They have a new product where they sell their lock and stock and you drop in your TC Hawken, Lyman Deerstalker, and other barrels into their set up.
