Oh yeah, I was going to mention that, in case you buy one used. I have no problems at all firing regular Rival rounds from my Orbit and Meteor, but there are a LOT of reports from people who got them early that the breech is a lil' too loose for a snug seal so Rival rounds just dribble out when you fire them.

If you get one of those early-release ones, fixing it should be pretty easy. Same idea as the ubiquitous white Triad EX-3 that doesn't hold darts in snugly. Open it up and wrap some tape around the inside surface of the breech (or apply a ring of fingernail polish) to make it just an ever-so-slightly-smaller opening. Then it'll hold the slightly-smaller Rival rounds in place and form a tighter seal for better performance. (Caveat: haven't tested this myself with an Orbit or Meteor since mine were all A-OK right out of the box)
