>>6032912I've actually heard that Retaliator modification kits will fit Recon MKIIs, but you'd have to use a Retaliator barrel if you're dead set on a pump kit (which I heavily, heavily recommend). So you could have a color-scheme confused blaster, but that may not bother you. And there's always painting.
As for the issue with 18 round mags, yeah, the first batch of Recon MkIIs were incompatible with 18s, but the later batches fixed that. As for how you're supposed to guarantee yourself you get a fixed one, I dunno. Don't own one to know. I did read somewhere that Hasbro would send you a replacement if you got a first batcher, but that may not be true.
I literally have no experience with flywheels though. Yeah they're awesome, but like I said, my group is pretty casual, so a springer with a kick is all I've really needed. But if the people you'll run with are more hardcore with Nerf, a good flywheel is never a bad idea. The Stryfe seems like it's easiest to work with, as many, many people use them, but the Modulus, Demolisher, and Desolator are all pretty much Stryfes in different shells. The Stryfe is just preferred due to its compact size. Rayvens are popular too, but it's my understanding that they're expensive.
The switch is up to you, my man. Whatever you think suits your playstyle and your environment more. I've also never liked the concept of relying on batteries, even though my brother has a LiPo'd Stryfe that seems to last for days. It's just a matter of preference, really.
