400+fps KWA M4S Tactical for CQB?

[zollen]

I was planning to attend the upcoming CQB events, but I was surprised to find out almost all CQB's allow airsofts with max 350fps. Are there any easy ways to adjust the fps of my rifle on the fly?

nop...only way to change the fps would be to change the spring.....

You could always use the TM FPS reducer...but almost all field-owners dont allow the usage of that device....

spring swap.
had to do it on my gun.
unless you've got another mechbox, or a systema, or 2 ics gearbox uppers, sadly your S.O.L

get a secondary rifle or shotty, shotty are great fun for CQB there are some out there that can be purchased for under $400 or a secondary AEG specifically for indoors such as the MP5K or MP7
