At a recent gun show I purchased a Springfield armory scope mount for my M1A...Attached to that was a "Tasco World Class Plus" 10X40X50...I didn`t use it on my m1a...but was wondering if any one out there had any experience with one...I also have an old 6X24X40 on my .308 bolt gun...It seems to be of decent quality...I didn't buy it new so I don't know much about it either...any thoughts???
