I have found a CVA Mountain rifle that I can buy for what I think is reasonable money. There are a couple of problems though. The lock will not engage full cock. The adjustment screw for the set trigger seems to be missing as well. This is the older made in USA version and is quite attractive. It has it's share of surface rust, but it will clean up nicely. Should I consider buying this? The current asking price is under $100 and I think that there may be a little wiggle room...
