I' ve had a Buckmark for 10 years. I love it.

I' ve fired several thousand rounds through it, sometimes 500 rounds in one afternoon.

I have found that I don' t get any jams until I get to about 350 rounds fired without cleaning. At that point all I do is spray the heck out of it with WD-40, shake off the excess, wipe dry with a rag, then back to shooting. Once I get home I strip it down and give it a thorough cleaning. I think this is the best 22 auto out there. I' ve had the Ruger, but it would jam earlier, and wasn' t as accurate.
