I saw Kris' comment. Went out and bought $4 dollar bottle of 6 mm plastic BBs. They never stick like the metal balls. Keeps the seal when not in use. Thanks for the great advice Kris.
good product. worth 50cents. My bb's used to get stuck in the hole even when sprayed with oil. This BB is bigger, and has yet to get stuck in the hole.
these are nice to be able to purchase but ultinately a waste of money my advice: get an airsoft plastic BB and use it. problem solved and they work a lot better than the metal ones anyways
