I have an original spyder compact but its far from stock.
my setup:
Halo hopper w/stock chip...upgraded internals
three different cal. barrels for paint swelling
two 24 oz co2 tanks for mid game air change
hallowed grip frame for lighten the load
dead on red dot reflex scope
rear cocking after market bolt
custom job on the trigger:
a personally machined reed inserted under the firing bolt to shorten hammer pull
a personally machined plate in front of the trigger in order to shorten the pre-pull
a nut in the rear of the trigger in order to shorten the post pull
Overall i have less than a 1/16 of an inch trigger pull.
i have done the impossible. i have a walkable mechanical trigger that puts out between 13-18 balls per sec. All my friends think that i am a serious mad scientist with an extreme love for paintball. there for they have named this gun Frankenstein.
