Alright boys, my ICS needs some diagnostics done on 'er.

Gun History:
Purchased second-hand from a reputable member on ASC in January 2008, its FPS was 290 which was weird as he had upgraded the internals. Have not had it touched until TAC09 when the spring was replaced by a gun doc with the (supposedly) same strength spring (Modify S100), I was told that the spring might have been too used/broken down to sustain FPS. With the new Modify spring the FPS dropped to 280, again I was puzzled. New spring has seen less than 1000 Rounds since then.

I changed out the stock Piston/Piston head for a Mad Bull Piston with full teeth and a Modify bearing piston head. The gun now chronies from 250 to 320 using BB Bastard .20's with the hop up completely off and a fully charged battery.


Barrel: Madbull Black Python Tightbore 6.03mm
Gears: Stock ICS (Metal)
Spring: Modify S100 (should be at 370fps)
Spring Guide: Unknown V2 with bearings, probably systema
Piston: Modify Polycarb Full teeth.
Piston Head: Modify Polycarbonate Bearing Piston Head
Tappet: Stock ICS
Battery: G&P CRANE 9.6V 2200 mAh
Bushings: Stock ICS
Shims: Systema Shims
Cylinder: Stock ICS
Cylinder Head: Stock ICS
Nozzle: Stock (I assume)
Hop Up Unit/Sleeve/Bucking: Stock ICS

Any Ideas WTF is wrong with it? its become a real pain and I swear it is cursed.
