  1. Sadly in in Southampton, and I was looking at getting a mosfet fitted, and found a completly upgraded gearbox, so I'm probably just going to buy that and then I can tinker and learn from the gearbox I already have,
  2. Just going to buy a new gearbox, thanks for the help lads
  3. To be honest mate, I don't have any idea how to take this hop up apart, just looks like solid metal to me. Will try that test tomorrow Forgot to attach I managed to take the hop up unit apart and the bucking looks good to me, no noticable wear on it at all
  4. Yeah feels like 300+fps of air ( compared the air flow to my Tommy gun ), so your thought would be that the hop up is the issue,
  5. The spring was a ASG m100, and the Piston seems fine, pushes all the way and then the spring will push it back fine
  6. I can't see any signs of damage, it was pretty easy to get to the box, the hop up looks good and fits right to the nozzle. The fps was around 230 as I accidentally cut to much of my old spring off. I just did a couple test shots as I put it back together, didn't bother cronoing as I could have caught the bbs they were going so slow. I have just noticed that the Piston (maybe) is not going back where it belongs every time, picture will be below as a picture says 1000 words.
  7. Yeah the spring is the only thing I have touched, it's a quick change system too so I didn't even have to open the gearbox to do it, thanks for taking the time to help me out with this mate
  8. I'm a twat 😂😂 have just put the lower receiver back on and as you said it looks fine, I guess I'm just looking for issues now, as I thought that might be the reason the fps has dropped so rapidly since I put the new spring in, the gun is a Spartan Delta SX18 M4, any ideas on why the fps could have dropped would be amazing, thanks for your help mate
  9. To be honest mate, I'm new with internals, so I could be wrong but is this what you mean??
  10. As you can see in the pictures, the spring will pop up or down, sadly I didn't realize this when I first put the gun back together, it only cronoed at around 150fps, the spring is meant to put out 350fps so I'm hoping this is the issue, as the gun was working fine before hand
