I.ve been shooting pistols since I was 12; I'm 66. My first shotgun at 14 was an old Harrington Richardson .410 single breakopen. The first and only automatic I.ve shot was the M16 in the 1970's. I received a Hi-point 4095 as a gift. It came with a red dot and iron sights. I have NO IDEA how to sight in either; but would like to have the red dot as I'm 66 and can't see worth ****. ANy instructions would be greatly appreciated.
