Yup, definitely a good choice. I have the blowback MP5 and it's the best gun I've ever bought, range is shorter than I'd like because of the barrel, but it's a CQB gun, so I can't complain.
People recommend G&G to new players because they're practically flawless, cost next to nothing and easily match up against the higher end brands, I've considered buying one myself. G&G are the one company I've never had a single problem with. I'd actually say G&G were THE best airsoft company with regard to reliability and out of the box performance, from my own personal experience anyway.
