It would be hard for me to nail down a favorite .22LR rifle. I just looked in my vault for a quick look and counted nine .22LR rifles.
The flavor of the month right now are my two Ruger 10/22's. The one on the left is my new 10/22 Takedown LITE and it is so much fun to shoot. The one on the right is my 30+ year old 10/22 that just went through a major overhaul including a new 16 inch steel threaded target bull barrel and all new trigger guts in the original aluminum trigger housing. With sub-sonic rounds both of these are my go to Silent 'Possum Slayers for varmints that slink around the hen house at night.
