SPRING GUIDE: Plastic Ver. 3, thats right, Version 3. I put a System Ver.3 in it.
BUSHING: Plastic, replaced with Guauder Steel bushings
SHIMS: Excellent job on the shimming of this rifle.
MOTOR: No name brand, but can pull the SP120. I replaced it with a Systema Magmum Power.
SPRING: M100 or M110.
TRIGGER: Metal, no need to replace. (No one sells them seperatly anyways.) :P

PISTON: Ver. 2 Plastic
WIRES: Good enough.
PROS: Easy the upgraded, once you get in the rifle. Affortable, Solid, Awesome!
