These are great little guns and a group of us, wait for a rabbit snow every year, when we take these out on a special hunt. All that we use, are these 24's. Of all the ones I have owned, there has never been one that didn't have a problem of some kind. These are favored by some collectors that have more than one model. You can still find replacement parts but you have to work at it. One of our group, makes some of his own parts.
Be Safe !!!
