Guess I post my 2 cents:
I never handle an AEG I'll give you that, spring and gas stuff mostly.
I'll never understand why people keep complaining about the cons of GBBRs (some are fair critisism I admit)
1) Mag Capacity...Dude why don't you just go play paintball in spray n pray, the whole airsoft thing is real sim, 30 rounds should be plenty. (All 3 current have mags can give 2X 30 rounds on auto in 1 charge, including Magna)
2) Accuracy, alot of the complaint comes from the hopup, go bug tm to make it, Im sure it won't be a problem anymore, as for right now Magna has Prime Hopup which is really really good but $75USD. The other blame is recoil which makes me argue even more for real sim.
3) Firepower, lemme ask you which modern military train soldier to engage in auto all the time? Auto is only for covering fire and storming. Semi auto is the way to go.
From Arguement standpoint Im gonna use two airsoft:
Systema PTW 2008 Max (Lipo mod) against
Prime DIY (you can get Bomber or Inokatsu for fac built) GBBR
Pro Milsim: Magna system wins hands down
Pro Spray-n-pray: Systema PTW
As for temperature problem...heres something, using Gas vapour chart of CO2, NPAS, and Pro-Win mag it is theoratically allow GBBR use in Winter. Here goes:
Pro-Win can handle 500psi easily, with NPAS you can reduce fps (might want to set to like <5% instead of 100% power) at temperature below 15 you can safely (on paper) use liquid co2 into mag. -25-30 is the prime temperature...If thing goes right basically GBBR (magna) cannot function: -10 to 15
