As a long time paintball enthusiast; I always choose to make the drive out to Mesa Paintball before practices and tournaments. Many paintball fields are "BYOP" and Mesa offers fresh paint at really strong prices. Placing a bulk order for my team is easy. I just call Chris or Derek and they let me know a few choices on the paint menu. No broken balls or dimples, quality has always been top notch. There IS a difference between Marbalizer and the paint you can get at a sporting goods store.
When my gun breaks down MPS has provided me with spectacular technical work. I remember one of my guns only needed a fifty cent o-ring, but I could not diagnose the issue myself. Derek could have easily mislead me charged me for a full rebuild. Instead he swapped the o-ring and only charged me for the small part.
MPS's selection of paintball guns and parts is somewhat eclectic. While they don't have every single modern high end most of the mainstays are present. Combined with some oddities like the Dye NT and the original classic Intimidator there are plenty of new and used guns to gawk over. I just took home a perfectly tuned DM6 and it's 2016! All of my experiences have been overwhelming positive and I will continue to give Mesa my business.
