for a new player, the CA.
its a bit cheaper, and easier to work on. (gearbox wise) It also has a safety (that works) and can accept standard M16 mags. Also weighs less.
Ive owned and heavily used a CA249mk2 last season. This year, its seen very light use. On stock parts, it shot very nicely, and lasted well over 15,000 rounds before requiring minor repairs. but those repairs were caused by user error.
