I have a "cheap" Glenfield 25 that was given to me several years ago with which I just shot a 230-8x at 25 yards with a Glenfield 4x15 "really cheap" scope and Wolf Match Target - this was the first time I shot the USBR targets with this rifle. I'm looking to upgrade the scope to something better but not spend a lot of money (e.g. normally I'd buy a Leupold for my better rifles but that seems it could be overkill for the Glenfield even though it shoots reasonably better than I expected). Any suggestions for a good scope that I'd use for 25 yards? I would prefer something with an adjustable objective that will go down to 25 yards. Also, any suggestions for what kind of rings to use with that scope? Thanks in advance.
