Spring change
 

Hey everybody, i want to change the stock spring in my G&G CM16 SRS and upgrade it to a M120 spring, question is,
should i or do i have to change out anything else? Keep in mind the SRS is completely stock.

Thanks all!

step 1: don't fix what aint broke unless you know exactly what it is you are trying to achieve with the new spring
step 2: research what each part in the gearbox does and how it relates to the parts that mesh with it
step 3: make your decision after considering the above points

Hello, you normally want to change your spring to help with FPS. If you are shooting too hot for certain fields then you would downgrade to a lighter spring and vise versa. If you need any help with this you can contact me by going to my website at www.OrangevilleAirsoft.ca

Thank-you
