So, my first emag is being shipped to me now. According to the previous owner, the gun has been sitting for about six years. Other than going through the valve, is there anything else I should look to service before I air it up and let it rip? I'm slightly concerned about the batteries. Two included. But, after sitting for that long, what's the chances they're gonna work properly? Also, is there anyone I can send this to for a software update? I'm aware emag boards are most often found sitting at the end of rainbows and the leprechauns aren't often willing to let them go. So, what other options do I have? Thanks!
