Sniper too hot!

[Aj698]

Hi all,

 

Looking for advice for a SA-S03 High Velocity pew.  

 

Upgraded hop rubber to Laylax purple Nine ball and rounded Airsoftpro cylinder head. Airseal is now awesome but it running hot (379fps on .43 bb's).

 

Any thoughts how to reduce to UK limit of 340fps??

 

Thanks in advance 👍🏻

Cock it and leave it over night and see if it drops the power. Failing that trim the spring.

Those numbers work out to 2.87 Joules, well over the 2.4J limit (which is equivalent to 500fps with 0.2g)

Better leave it cocked for a few days...

Cheers!  Will try that tomorrow and see if it fairs Tuesday night.

I doubt you’ll lose 40fps by leaving it cocked. Probably need to clip a coil or 2 off.
