The Ruger 10/22 has been in continuous production since 1964.
It is one of the most successful rimfire rifles ever made.

A Rimfire Companion
Bill Ruger and designer Harry Sefried built the 10/22 as a rimfire companion to Ruger’s .44 Magnum Carbine. Its short, handy lines echo the M1 Carbine, and its flush 10-round rotary magazine set it apart from tube-fed .22 rifles of the day.
The Rotary Magazine
The BX-1 magazine holds ten rounds in a rotor instead of a stack, so every round presents to the chamber the same way. Ruger later added a clear BX-1CLR, the curved 25-round BX-25 and the 15-round BX-15, all with steel feed lips.
A Platform, Not Just a Rifle
Because the receiver, barrel, stock and trigger group come apart easily, the 10/22 became the most customized rimfire in the United States. Today a shooter can build a complete 10/22-pattern rifle without a single Ruger part.
