ive never heard of mr paintball....is it a local shop? anyways....you cannot discuss it openly on this forum, as we do not allow sites/retailers other than
www.xpaintball.com to be posted. (i would read the rules if you plan on hanging around for a while)
it would also help if i knew what model of gun you were talking about, since most electric trigger frames can bet set to automatic and there are literally hundreds of guns that have the "auto" feature. please be specific.
