The Ruger 10/22 is a semi-automatic rimfire rifle chambered in .22 Long Rifle.
It has a removable 10-round rotary magazine which allows the magazine to fit flush with the bottom of the stock. A magnum version, chambered for the .22 WMR cartridge, was made from 1998 to 2006, and a .17 HMR version, the 10/17 was announced in 2004, The 10/22 was immediately popular upon its release.
It is very popular for small-game hunters and those who want an inexpensive rifle firing inexpensive ammunition for target and plinking use.
This popularity has led to many after-market modifications being available to improve performance, augment the rifle's looks, or increase its magazine capacity, leading the 10/22 to be one of the most customizable firearms made.
The standard 10/22 ships with a black 10 round rotary magazine.
Ruger has also produced a clear, polycarbonate 40th anniversary edition 10 round magazine as well as a five round rotary magazine (for states that restrict magazine capacities).
Custom manufacturers also make "clones" of the 10/22, which are similar in design (most parts will interchange) but built to much higher specifications and costs.
The 10/22 barrel uses a unique two-screw, V-block system to attach the barrel to the receiver, making removal and replacement of the barrel (which would require a gunsmith's work with most other rifles) very easy.
Remember back in the 60's no one used (had) computers and inventory control was done the old fashioned way via type written reports. Although the production of 10/22 rifles has been fairly well documented.
I was told that because of the vintage it may have higher value to a collector. Sorry to tell you its not a first year produced rifle.
According to Ruger your gun was manufactured in 1965, but don't feel bad as Ruger only shows 452 guns being manufactured the first year in 1964. History/RI-10-22With it being a second year gun, and the condition it is in, I would still suspect that a collector might be interested in it. So when I say that the value would be in the 0 - 0 range (to a collector) that is only a best guess on my part. I saw the S/N listing for Ruger which suggested that the gun was manufactured in 1965.
Even if Bill Ruger (read more about the history of Bill Ruger) really did view this as some type of afterthought to the .44 Magnum Carbine, it couldn’t help but to succeed.
After all, who can resist a sweet-handling .22 rifle?
