Well, Enos seems to be skilled at putting smaller springs in. Yes, that spring is a pain for me, and I lost the first one at the field. It flew off once, I found it in the grass. Then I forgot to put the barrel adapter in and had to take it apart again. You can do the click pen spring mod to your trigger, then use the trigger spring to hold it in (stretch it a little). To completely replace the lost spring, you can call Tippmann and ask for a  long trigger spring (the one you replace with the mod is the short trigger spring). The long trigger spring is also referred to as the sear spring. I use a small flat screwdriver to pull the spring back, then quickly manage to slide the tombstone adapter latch back in place. Once it's sitting back in place, you have to hold the spring and push it down so it's somewhat secure. Then reassemble the halves quickly but carefully.

Enos- for the cocking knob spring, just leave it overhanging past the groove. When you put the halves together, just hold them together somewhat firmly and use a screwdriver to slide the spring forward into the groove. With the firm pressure, the halves will go together right when the spring is in place, thus keeping it there.

It was a steady hiss nefore the fart noise.
