Do i need to apply any lube to the inner cylinder where the o ring & piston slides through?
I recently added a new 1.25mm spring and o ring to my j10, but it seems that the fps has dropped 20-30fps bellow what i was getting before.
And thinking i have not lubed something or did something wrong.
Other things could be the electrical wires getting squashed when trying to fit back in the receiver, can now see a tiny bit of the exposed wire (i will use electrical tape to go over that)
The ■■■ still fires well, i only found out chroniing it, and would have believed it was fine up untill that point.
