Have you ever wondered what year your trusty old Ruger 10/22 was manufactured?
The chart below shows the approximate first serial number shipped for the indicated year. This number should be used as a point of reference only. It is not necessarily the very first serial number shipped, but it can be used to determine the approximate year your Ruger firearm was shipped.
Ruger does not produce firearms in serial number order. There are occasions when blocks of serial numbers have been manufactured out of sequence, sometimes years later. Also, within a model family the same serial number prefix may be used to produce a variety of different models, all in the same block of serial numbers. And in some cases, models may be stored for a length of time before they are shipped.
Traditional Factory “Iron Sights” ~.6″ Sight Height Above Bore:
- If the farthest distance that you will be shooting is 50 yards then you will be be served with a 12 yard or 15 yard zero.
- If you will be shooting you rifle past 50 yards and out to 100 yards then you will be best served with a 10 yard zero.
Optic Mounted With Aiming Point ~1.5″ Sight Height Above Bore:
- While the 25 yard zero is very attractive, I would still recommend a 20-yard zero. While there is a very slight penalty of higher apogee of flight with the 20-yard zero, you get almost one inch less drop at 100 yards.
Dedicated Or Converted .22LR AR-15 Style Rifle, 2.5″ Sight Height Above Bore:
- Zero your .22LR caliber AR15 style rifle, or AR15 with .22LR conversion kit at 25 yards.
- From approximately 13 yards out to approximately 89 yards the bullet’s impact will be within +/- 1″ of where you are aiming.
- At 100 yards you can expect the bullet to impact between 2″ and 2.5″ below your point-of-aim.
