Ca m249 mkii downgrade spring

[gettothechopper]

Hi I recently bought a CA M249 MKii with a madbull tight bore barrell. On its first skirmish it chronod at 351fps but the limit was 345fps so couldnt use it. Anyone got any ideas on a downgrade spring and where to get? Thanks in advance.

If its got the quick spring change feature like the A&K, it should take you all of about 1 minute to change it.
Search on youtube for m249 spring change as vid on there showing how to do it

Do you just want to loose 6fps ?

could you not just extend the barrel with a bit of tube to lower it ?

or cut a coil off the spring?
