The 880 was a very good design with many variants offered by Daisy. These are some of the rifles based on the same design.
The 822
The Daisy 822 is a single shot .22 caliber pellet rifle that is based on the same design as the 880. What makes this rifle exceptional is the wood furniture and metal components, it is a very well done rifle. The internal workings are the same as the 880 and can either be Old or New Style just like the 880.
Daisy 881
The Daisy 881 is very similar to the 880, the side covers are metal and often silver. The 881 has the exact same internals as the 880 and every one I have worked on has been the Old Style internals.
