Ok, so I am sure the answer to this is buried somewhere in thousands of posts on ASC.

Here is the question.

I just rebuilt one of my AEG gear boxes and this one is a masterpiece. SO SILENT.

I really took a shit load of time and shimmed this from the motor back back on. Proper grease etc etc.

If you shoot this with a pilow over the barrel, it is nearly silent.

So here is the wierd part. I do not have a silet piston head. Just the standard piston.

So going back to my school days on pneumatics and hydraulics, is it possible there is "air spring" left in the piston when the pistion goes smashing into the cylinder head?

I am beginning to think this may be the case. My thought is when all airsoft pistons are discharged there is NOT a rock hard contact. If there is a good seal I am thinking there is an air spring effect for the last small potion of the stroke as the piston is discharging the air.

Thoughts or data ???
