By the mid 50s, Remington went with a grooved receiver for scope mounting, but ours is a late 40s without grooves, so no way to mount a scope. Instead, I added a Skinner barrel peep.

This is no cute little carbine, by the way. It's a full size adult rifle with a 24" barrel. The 550 ran from 1941 to 1970. The -1 indicates that it has the improved extractor that was changed a couple years after the 550 was introduced, so it's unlikely you'll find any other version.
The most notable feature of this semi-auto 22 rifle is the floating chamber. This allows the 550-1 to shoot Shorts, Longs and Long Rifles, interchangeably. Yes, a semi-auto 22 that can shoot Shorts, Longs and Long Rifles. That's really remarkable for a semi-auto 22. Came in handy back during one of the 22 ammo shortages, since we had a lot of 22 Shorts in our ammo inventory. The Remington shot them great.

But would it shoot 22 Short CBs? That's asking a lot even for a 550-1. Sure would be handy, though, since I've been using CBs for my plinking, recently. Stepped out on the deck and loaded 5 CB Shorts and gave it a try.
Pop, pop, pop, pop, pop! Talk about fun! Yup, the 550-1 can even cycle CB Shorts. Trigger pull is actually pretty decent, too.
There was a time when you could snag these 550-1s for about $150, but fans of these old school, all steel and walnut 22s have been buying them up, so you'll have to spend a bit more, now. If you can find one in good shape with a grooved receiver, might want to grab it before I do.
