Plastic mags or metal mags? If you got the plastic ones, you got an old problem one. I think rem will send you metal mags for free. Walmart has mags for it too (at least they do here). Go to rimfire central. When I was researching those they said they had a lot of problems with the bolts into the slide rails being too tight and causing the rifle to stick. Loosen them all the way up and retighten just enough so it wont bind.
