I picked up a four screwed patch box .50 caliber CVA Mountain rifle about a year ago for $100.00 at a rendezvous. It was missing the butt plate, the strange greenish finish on it was beat up and had a load stuck in the breach. Found a NOS butt plate on flea bay for $20.00, got the old charge cleaned out, gave it a refinish and have a nice shooter for under $125.00. Most of my CVA rifle collection was acquired needing some type of work to get them to shoot but they are a lot like a Chevy, easy to work on and reliable once fixed.
