Just a bump for a great little marker. Love mine.
BTW, I recently found that the BT-17 bottom line kit fits this ACP 2.0 perfectly for about $$22, for folks who want to run it on HPA.
Plus the barrel is Spyder threaded, and I just got a 3.5 barrel from china via ebay for $8, which just needed an added tank o-ring to seal it better. Made it markedly quieter, too.
It's also pretty easy to drop First Strike rounds in the breech with the magazine removed.
