For reference, here's a family photo:
All three have threaded barrels. The target rifle (bottom) came from the factory that way, but I had to have the other two done by my gunsmith. The top one is the 10/22 that I got about 40 years ago. Quite possibly my all-time favorite gun. The middle one was intended to be The Squirrel Sniper, but then I shot a buddy's Target model, and I just had to have one. So the middle one has had its scope removed and gone back to a basic, iron-sights plinker. The bottom one, obviously, it my target rifle.
