i have a mossberg model 125 .22 s-l-lr single shot bolt action rifle that had been passed down to me. from what ive researched, i can only guess that it was made in the mid 1930's but the model is rare. its tapped for a scope, and i want to find the mount for it but i was just wondering if anyone knew anything about it because i havent been able to find any information anywhere else. thanks
