I'm looking for a low-cost, low-magnification scope for a pistol-caliber (.45 ACP) carbine that's for use under 50 yards with long-eye relief, ideally pretty small and light. I feel like a cheap .22 scope would do the job, but a lot of the ring mounts on those scopes are too narrow to fit traditional width rails. Any recommendations? Bonus points if vintage looking.
Been looking at this one, its $80 bucks and just about what I need, it looks like. It's an Osprey Global SD2.5X20DP.
