hmm, sure
it will be a Guarder spring.
Let me explain: I have a crappy aeg, and I think that the piston is smaller than a normal piston. The stock spring has 90mm, and the Guarder spring has 180mm. So I'll have to cut the spring.
I've just bought a new motor and I'm going to buy metal gears.
I want it to shoot around 290-300fps with 0.20g bb's. So what spring do you think I should get?
I'm thinking about the Guarder SP120
my reasoning (rule of three):
18cm -> 428fps
x cm -> 300fps
428x = 5400
x = 12,62 cm
So I would cut off 5,38cm of the spring.
What do you think? I really need help, haha
