Danger

The Spyder is not made to go full auto. If you do this you will probably chop balls and you may risk damaging the valve.

Method 1

This is probably the best method that I have seen so far. What you will want to do first is remove the trigger frame. Once the frame has been removed figure out how the trigger works. You will notice that the sear can be pushed forward. When the sear is in the forward position it is engaged with the trigger and when you decrease the pressure on the sear it is disengaged with the trigger. The idea behind this is to keep the sear constantly engaged with the trigger. That way the sear cannot go back to it's original position and reengage the striker making you pull the trigger again. Once you understand how the trigger and sear work remove the pin that holds the sear in place. When the sear is removed you will notice the hole that the pin goes through has room for about 2 pins. What you want to do now is place a piece of metal in the front part of that hole. However make sure that the metal pin will still fit. Now reattach the sear to the frame making sure that the sear will still move up and down when the trigger is pulled, only this time the sear should stay down for as long as you have the trigger pulled. This should render the gun full auto, one word of advice you will probably not want to shoot long strings of paint because the valve will need time to recharge.

Method 2

This method may also work but it is harder to do than the last one. You will notice that when you take the sear out there is a spring that makes it go back after the trigger has been pulled. What you are going to want to do is reverse the spring so that it pulls the sear against the trigger. Thus making the sear stay in constant contact with the trigger. I have no idea what to attach the spring to. It's just an idea that I came across, it would work so long as a place can be found to put the spring. I still think that the other method is the best.


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.
