I've got a red dot mounted on my Mini-14. I have the Weaver sight mount that replaces the rear sight. I had the B-Square mount that goes in the side plate on the left. I thought it was a piece of junk. The Weaver is much better and didn't break the bank. The scope is a Simmons. It is less than an inch in diameter, but I think it works fine. With the magnification power of 1X, I sighted it in at 50 yards- mainly cause I couldn't see the dang target at 100 yards with no magnification. Ideally, I wish I had the Ranch Rifle as it has built in scope mounts, but my set up is satisfactory. If I remember, I'll try to get a pic, but it's late and my camera is in my car and the alarm is on and my wife is sleeping, so...
