G&G Firehawk Stock Spring?

Probably about a m110 to maybe m115-ish

Should put you at about 360 - 377fps but due to 120mm barrel you lose a fair bit of fps

Most G&G's are about 330-ish but I got one FH untouched hitting about 347fps

(way over the Mall's 340 max limit)

If you stick a longer barrel on there the fps will likely increase a fair bit

(though if you go nutz you won't have the cylinder volume due to the short port on cylinder)

Most likely if you got a bit of a drop in fps then check seals and pop a bearing spring guide in maybe

Thank you for the response. The reason I’m asking is I just put a laylax m120 spring and spring guide into it, but when removing the stock one it looked alomost identical.

I was actually looking into extending the barrel, will look further into it today. 

 
Update: Decided to go for a Madbull 6.03 x 247mm barrel, unsure if my cylinder will have enough volume. Already have a decent length mock silencer to cover the extra barrel length. Will replace out the cylinder if need be.

 
Did you ever get this set up? Im in a similar position what was the original  barrel lengh to begin with? 

Im planning on going from 120mm to 247mm and im guessing the cylinder wont have enough monkey

 
I added a 239mm Prometheus, upped from 330fps to 345/350 fps, no other upgrades just a dummy silencer to cover the length. 

Improved range accuracy to go with it.
