Miss information^^^That Nikon 3x32 is a nice scope but to mount it on your Mini 30 you will need the Rail that clamps on to your Mini 30's reciever to accommodate the length of the Nikon scope. Plus the BDC is calibrated for the .223/5.56. Any nice 1-4 scope will work or a 2-7x32. I have a 2-7x32 a Redield Widefield on my Mini 14. Good Luck!!!
