MP5K + Dampner

So I got an Mp5k off of a friend for dirt money. She wasn't shooting right (BB's falling out of the barrel) so I took her apart and put in a damper piston head like this The o-ring on the original head was screwed, causing it not to cycle properly),r:0,s:0

Now she is cycling fine, and there seems to be a good bit of air coming out the barrel.

However she is only shooting 160fps with .2g bb's! Would it be the new piston head? Or the plastic air nozzle looks a little messed up on the inside? Or would it be the hop up chamber? (I took that apart too) :shrug:

(Spring is fine, cycling fine, and sounds the exact same as my other one)

Thanks and sorry for the long question :tup:

Was the spring been decompress? If it wasn`t your leaking air from somewere.
No, the spring is fine, and I don't see where it could be leaking air.
Did you accidently switch the cylinder around?
That really sounds like an air leak issue or air nozzle problem.
Just test the airleak of nozzle by pushing the piston inside the cylinder, and keeping the nozzle shut with your finger, the issue might be with the nozzle->hopup.
Just google for some mp5k nozzles and see if your nozzle is alright.
