Howdy, folks. As I mentioned in the "New Members" post I put up, I'm looking into PCP for the first time in my life. I've been shooting airguns of one sort or another for most of my life but I'm in kindergarten when it comes to PCP. During my online investigation I've run into Air Arms references and two models come to my attention. I see that they offer an S410 and an S510 - but I don't see much (any, right off the bat, but at this point I'm not sure what to look for) difference between the two other than the designation. I even found one video on Youtube with a note that "the S410 was renamed S510 for the U.S. market." But they both seem to still be on the market and I don't see what a change from a 4 to a 5 would make it more appropriate to the U.S. market - IF the change is only a model designation with no distinct features. Reading a tiny bit on a U.K. forum I got the impression that S410 is a bolt action and the S510 is a side lever - but the pics I've pulled up don't bear that out, the S410's I've seen seem to have the side lever mechanism too. So, what differentiates the one from the other?
Thanks, guys. And I'm sure I'll have more dumb questions to ask as I attempt to polish my tiny reservoir of knowledge on the subject of PCP.
