Period of Product Use:
Pro master, with stock barrel and feed neck, Velocity Jr. loader, and 45/68 Crossfire carbon fiber tank.
A new feed neck is a must--mine spins like crazy--, new trigger--depends on your personal preference--, and a barrel couldn't hurt.
The Pro master is: light, compact, durable, fast,and quite accurate.
Have to watch the gauges. Check settings when you get a Pro master. Feed neck.
I really like the Pro master, it is durable, fast, and compact, everything a paintball gun should be. I like how you can take the bolt out and field strip it with no problem. I would say that you NEED to get a new feed neck the stock feed neck is very large and doesn't fit many loaders. I can also say that i don't like the trigger but that is my preference(you might love it!).
Overall i really like my Pro master, and if you keep it in good condition it could be a great investment for you.
