Lukeberto01 Posted February 22, 2017 Share Posted February 22, 2017 Hi everyone, my new gun the M4 SRT-03 spartac, I chronoed it and it was 410 FPS which is to powerful for a full auto rifle, so I bought a new spring and I was suppose to make the FPS 360 FPS but when I chromoed it it was 140 FPS please help ?? Thanks in advance, Link to comment Share on other sites More sharing options...
Supporters Sitting Duck Posted February 22, 2017 Supporters Share Posted February 22, 2017 140 is pretty dire - bad air leak the nozzle is not sealing against the hop if you just replaced the spring most likely the nozzle is misaligned - gearbox tipping upwards or hop unit not pushed firmly backwards to seal with nozzle when fired = air pissing out who changed the spring ?

Hangtight Posted February 22, 2017 Share Posted February 22, 2017 Well, you've invalidated your warrantee. If it was shooting hot you should have asked the retailer to downgrade the spring to your preferred limit. Link to comment Share on other sites More sharing options...

Supporters Samurai Posted February 22, 2017 Supporters Share Posted February 22, 2017 Take it to someone who knows how to work on airsoft guns. It's not something one just magically knows how to do with a hammer. Link to comment Share on other sites More sharing options...
