Yeah but knowing its my first AEG, that it costed me 100$ and that I will buy a good one in like 1 year, I would like to try fixing it myself, even if my knowledge is really poor and that there is a risk of making things worst.
I know krakens arent good airsoft guns, but the gun cant just explode by itself, there are parts in it that have to be replaced, or modified (shimming, greasing).
And for the spring thing, I had a 300 fps spring pistol, and I let it cocked for like 1 week, and after that it was shooting like 175 fps...
Loss of air compression looks like the most reasonable answer, it is the piston head, the o-rings or what? Can I fix it ? What parts should I buy? (excuse my noobness)
