VERY light trigger pull(click your mouse, okay thats what thetrigger pull is like)
Good stock barrel probably one of the best out there
The rate of fire is insane
Doesn't chop balls
VERY VERY easy to use
The instruction manual, but the website (www.m3paintball.com) has videos that explain everything.
Uses up 9v. batteries fast(after about 1500 trigger pulls the marker doesn't always fire)
The stock barrel is pretty loud, the accuracy makes up for this though.
This marker is good for beginner to advanced. The light trigger pull, great rate of fire, stock accuracy, and that it is easy to upgrade make it a very good marker for the money. Remember to keep it well oiled and clean and it should last a long while. If you want a new marker i would definitely suggest you at least take a look at this.
