I don't know whether its rail or direct mount. Look at the bottom of the asa, If there are 2 screws side by side going into the frame then its a direct mount, if it slides onto a rail milled into the frame (I think its a weaver) then its rail mount. You just need to see if its either because rail mount ASAs won't fit onto direct mount frames without an adapter. It looks like its rail mount from some of the pictures, so just find a cool looking rail mount. I know the POPS is rail mount and comes with an adaptor fro direct mounting.
The replacement takes less than 10 minutes, all you need to do is remove your asa, and mount the new one. You can reuse the fittings as long as they aren't leaking already and you may even be able to reuse your old Macro as well.
Yes, any Asa will work just make sure its rail or direct mount. I never liked the tiny little knobs Dye puts on their ASAs.
The first generation of Crossovers had a trigger that was heavier with a stiffer spring. But there was a free upgrade released to change the trigger to the newer version, and all stock released from that point on would have the new trigger. This is the same trigger that the XVR has. If you were trying an older Crossover that did not have the free upgrade, the trigger would feel stiffer and heavier than the current one. That said, without the spring is like 3x better with both the old or new trigger.
A kid at my field has/had one, Maybe he had this Stiff spring because I wasn't impressed at all. That's just me though. Playing for 8 years and working at a field I get to shoot the latest and greatest, so maybe I'm a little biased. Also, hes a kid and it was down all the time, perhaps it just needed a good once over to get it going nice.
Doiing a bit of snooping I dunno if it was a standard or an xvr, I know it was ano'd green though. He'll probably be at the field today so I'll ask him.
When you put your finger in it put it all the way in....
Honestly the bolt on my enmey was softer than nearly any of the other cheap guns I have used. Sans Agd lvl 10. It worked kinda similar to the lvl 10 because of the second Oring on the bolt stem thing. Wont cycle fully unless that oring travels the full way.
I even tried my small finger and it was fine, Watching most spyders I wouldn't even try them. FTS.
