I'm a bit of a noob.
I'm looking to buy a G&G Combat machine AEG CM16 Carbine. Zerooneairsoft offer an added m90 or m100 spring for an extra £35. What does this do/affect? Would anyone reccomend me buying this extra?
Also is this gun good enough on it's own or do I need to buy a good hop-up to increase accuracy?
And also what is the best battery for this gun?
Thanks a lot!!!
