Nail or similar round object (diameter of a reciever roll pin)
something to cut the nail
Cut the nail point and head off. You must make it 1/4". Unscrew the left side of the lower receiver. Make sure to leave all the roll pins in the right half of the receiver along with the screws, springs, trigger, and sear. Cock the gun carefully. (make sure nothing flies out) Notice the small gap between the sear and receiver roll pin that it swivels on. Put the modified nail there. It should fit snuggly but not restrict the movement of the sear. Keep the gun cocked. Replace the left half of the receiver and screw it into place. You can now dry fire the gun. See how the sear constantly engages the trigger? This is what allows it to be full auto. Connect your CO2 and hold down the trigger for an amazing display of firepower. You would probably want to get a motorized hopper to keep up with the rate of fire. I noticed that a VL-200 jams up and the gun shoots air. I don't believe that this is because of the quick cycle rate of the gun (stock prolite is 300 rpm) but rather from the fact that most hoppers jam up often if not jiggled. you probably would want to limit your rate of fire to three or four shot bursts, as I've found it chops up balls if you don't have a constant feed of paint.
Warning. The tippmann may fire faster than you think. An aggitated hopper may not be able to keep up with the amount of firing coming from the prolite/carbine. I must say this is the problem they had with the tippmann F/A. You will have full auto, but may chop alot of balls.
PLEASE READ: it is not recommend to make any semi auto marker into an automatic. It can damage your internals of your marker and replacing the parts may be expensive. The best thing to do if you want to shoot faster is to reduce the trigger pull. This way you can launch more in a shorter period of time. There are trigger mods in the INFO section of this page.
