Hey guys just read most of this thread, but i dont think anyone has the same problem im currently having, so here we go :P

I just recently got a brand new KJW KP-06 and i absolutely love it, its one of my favorite sidearms just because of its power, recoil, and quality. (yes quality, its a very nice piece for the price)

So heres the problem and i can already tell you guys it originates from the valve bulb in the loading nozzle. The problem is that when i dry fire the gun it cycles just great with amazing recoil (resembling a .22), then when i try shooting it with bb's (ICS .25G Bio bb's) It still fires (320FPS) but the recoil is severly reduced and the gun struggles to make a full cycle. I put in a WE stock bulb in the gun and it functioned great but the downside of that bulb was that i only got 275FPS out of it so what do you guys think? BTW im using the stock KJW bulb.

Non Stock parts include:
Falcon 162.5mm 6.03mm Barrel

UPDATE:
alright so quick update, i took apart the hop up chamber, gave everything a good cleaning, re-adjusted the hop rubber to sit higher in the barrel (I.E. hop up turned down) and it definitely helped! however the difference in recoil is still noticeable, also one more thing to add from hop up being halfway on (320FPS) and hop up being turned down to about 1/8-1/4 way (310FPS) this concept in gas guns might not be clear cut, but my explanation is that, having less available area (hop up turned up) will increase pressure in the barrel thus resulting in a +10FPS rather than a 10FPS reduction, can anyone confirm this?


Update:
so i wasnt able to exactly pinpoint the problem i guess, because when i changed the KJW nozzle to a WE Stock nozzle + KJW Bulb, and stock WE piston head, it still had the same problem. So then i swapped out the KJW bulb for the WE Stock bulb and i guess it was a success! kick was reduced by 5-10% but instead of shooting 275FPS W/.25G, its shooting the 320FPS it was before i had this problem! So in short i swapped out the stock nozzle, bulb, and piston head of the KJW for stock WE parts.so to all KJW users i strongly suggest you swap out your stock bulbs for high flow bulbs or stock WE/TM bulbs!
BTW the stock KJW bulb i am reffering to is the blue plastic one with the crossed opening
