The Ruger 10/22 was introduced in 1964 and two years later, in 1966, Ruger introduced the first Sporter version of the 10/22 along with the full stock International version as options to the standard Carbine. This is a 1966 Sporter, the first year for the 10/22 Sporter.

These first Ruger 10/22 Sporters had the finger groove forearm stock, so everyone just calls them finger groove Sporters, though Ruger just cataloged them as the Sporter, since it was the very first 10/22 Sporter. The stocks for these first 10/22 Sporters with the finger groove were actually made for Ruger by S.E. Overton.

The last of the finger groove Sporters was produced in 1971. That short production run and the fact that the finger groove Sporter was just an option to the more popular and more affordable Carbine is why you don’t see these finger groove Sporter 10/22s for sale very often. That’s why I grabbed this one and, yeah, I paid the hefty going market price to get it. It’s in excellent condition, though.
In that same year of 1971, Ruger replaced the finger groove Sporter with the first Deluxe Sporter. This new Deluxe Sporter had a stock that Ruger made themselves. This new Deluxe Sporter had a checkered stock without the Monte Carlo and no finger groove. Very different stock than that first finger groove Sporter. Here’s our mid 80s Sporter Deluxe with the finger groove Sporter to show the difference. Much slimmer stock on the newer Deluxe Sporter.

Next gun on my 10/22 bucket list is a liberty (made in 1976) 10/22 Carbine or at least an early 10/22 walnut Carbine prior to 1978. The early walnut 10/22 Carbine was the first 10/22 I shot, back in the day.
Now to get out and have some 10/22 shooting fun.
