Ladies and gentlemen I am way out of my league in this forum. I started collecting guns as an investment 35 years ago ... then never sold one cause I like them all. I just started shooting hand guns maybe 10 years ago and I'm just now shooting / buying a few rifles. I want to put a decent scope on my S&W MP 15/22 that will serve me well at 50 - 100 yards. Teach me something .... when a scope is listed as "3-9x32" ... what do the numbers represent? Does 3-9x mean it adjusts from 3 to 9 power??? and is 32 the size of the opening??? and for shooting targets at 50 to 100 yards what would be best??? Told ya I'm a big dummy about these and most other things here.
