Re: Mr1 Firing Problems
Could be assembled wrong, or missing a bit, or tons of things, but I would probably take it back to the dealer to have it checked out, but if you plan on learning something about your paintball marker, try learning to field strip the thing yourself and putting it back together with the help of the MR1 manual.
Seriously, Spyders are pretty simple guns, with very few moving parts in them. Even a technophobe like myself can do it. Of course, if you're 16 or younger, I might have one of my parents help you out the first time.
