hw99s piston.

Is this in all hw99s pistons? http://abload.de/img/46ejn0.jpg

I gave my piston a good tap on the vice but nothing came out of mine.

I have put a new spring in that is supposedly a genuine hw one but its an inch longer than my old bent one.

Not in mine.

Cheers guys. If I look into the cocking slot on the piston, the bit the spring sits on is level with the slots end. Does that mean there is a weight in there?

If there is one its held in with a small o ring. Try and wiggle it with a pick through the slot, if it wont move its not a weight.

Its back together lol. I meant to look in with a torch.

Thanks nick. I will strip tomorrow and look.

Yes, very common! The new spring should mean you don't need them to make power.
