A couple years ago, I bought one of the M38 6.5x55 Swedish Mausers from the crop that happened to be circulating through the market at the time. I am trying to keep it unaltered in case I want to sell it as original but also wanted a handier rifle - so I bought a nice synthetic stock plus an LER mount and scope. The stock was a great idea but after numerous attempts, I found myself unable to use the long eye relief scope consistently (I could hit a target but groups stank). The LER mount bolts into the existing rear sight pocket and I was thinking of machining a conventional mount block to fit this area but extend it to the rear so I could put a regular variable power on it without drilling and tapping the receiver. That would generate a long moment arm and I was considering putting a jam screw in the mount to exert tension against the receiver and put the mount in tension.
Anyone have thoughts on the best way to do this? I'm considering using a low carbon steel then sending out for color case hardening to help with wear and make it look nice.
