Airsoft Canada - View Single Post - P90 shooting low FPS after spring upgrade

SG1-EVERETT · August 25th, 2007, 21:24

I had some success today after taking my mechbox apart about ten times.
I found two issues causeing FPS loss.
My DeepFire Halftooth piston was rubbing on the sector gear!
From the shine in the space beteen the gears it acting like a brake.
I swap back to the stock TM Piston and was shooting 372 FPS.
Also I have been using Radio Shack lube gel and start thinking it was too thick. Reading through the forums someone mentioned that cylinder lube can reduce your FPS.
I cleaned my cylinder and applied ceramic grease to the cylinder.
I also polish the piston guides with steel wool and applied ceramic grease.
Another tip from the forums.
I didn't have the bearing on in the piston so I put it back in.

Now my P90 is shooting a steady 390 FPS perfect.
