Update!!! took it all apart and got into the gear box, checked the cylinder air pressure with and without the nozzle. Tested with the plastic guard as I understand it pushes it away and everything seemed fine but I heated the O ring just in case and greased up. Also the hop up rubber looked in good condition but I thought may have possibly been dry and that’s the reason as you guys explained, so cleaned it up and greased it. Put all together after having some issues putting the receiver back on, the results are below: 0.20 firing average 325fps @ 0.98 Joules 0.28 firing average 265fps @ 0.91 Joules (did have one that fired at 286fps @ 1.06 joules which would be happy if that was consistent) The above results are probably correct with the spring that the shop provided me with as explained at the beginning which is suppose to give around 330 FPS with 0.20. (Even though I’d explained what I was looking to achieve) I’m thinking for myself to get as close to 295fps with 0.28 I’d have to buy a 110 spring which gives around 360fps with 0.20 and cut the spring if it’s going over? Or any other recommendations on how I could reach the desired fps? 🙂

Thank you everyone that has commented so far, going to test out all the above tomorrow and get some grease bought. Yes, I haven’t changed the barrel it’s stock, it’s just the guy at the Airsoft shop said with it already having a long barrel it should increase. However that’s good to know Roger about your experience. I’ll watch the videos on YouTube and will update you all! Really appreciate everyone’s help, thank you!! Will update immediately once I’ve done all the above 🙂

Hi all, I’m currently having an issue with FPS. I tested my M4 and it was kicking out 306FPS using 0.2 @ 0.84 Joules. (Stock) My aim is to get 295FPS using 0.28 as from what I understand that is the equivalent to using 0.2 and getting 350FPS. So I bought a Laylax Non-Linear AEG Spring MS100. What I was recommended by the Airsoft shop as they explained it would normally provide 330FPS using 0.20, however with it been a long barrel it would give more FPS. I’ve changed the spring and I’m actually getting 297FPS with 0.20 and 245FPS with 0.28. (Lower than previous spring) Strange how I’m getting lower FPS with a new spring. The rifle I own is: G&G AEG TR16 MBR 556WH with G2 ETU The site I go to has a limit of 350FPS for automatic, so I’d like to be getting as close as I can to the equivalent using 0.28. I’ve attached an image showing details of test and these figures are with no Hop-up on. Any ideas of where I’m going wrong or what I need to do? Any help appreciated. Thanks
