Ironically I've got one which I was just messing around with as you posted this. I paid £245 for mine as I imported it from Gunfire, so it was a lot cheaper,
but it wasn't working properly on arrival. The tech who had a look at it said that the downgrade to the power that was made by Gunfire was the issue, as they'd failed to put it back together properly. Even I could see this was an issue as one of the screws at the rear wasn't put in correctly. Anyway
@Luke NegAir who teched it for me (Negative Airsoft) put in a Perun ETU++ (which gives a lovely three round burst function) and disabled the electronic blowback for me, as there was a metal plate that was bent and was likely to fail at some point. I could put the function back, but I followed Luke's advice, which was it was the blowback was more trouble than it was worth. If you have some basic knowledge, a quick search on the internet will give you enough information to disable the blowback yourself.
How does the gun now work? Not bad actually. It was performing as well as my Kings Arms M4 and I got decent hits in the game I played. It also really suits the Brit loadout I've been building, plus it looks different - not another M4 in the game. The balance is OK as well. I've never run a bullpup before and it was OK to shoot. I appreciate these things are personal, but I quite liked it with the sling set-up. I use the G&G M4 mid-caps, just because the length seems to look more realistic, but it took my CYMA mid-caps absolutely fine as well.
Now the bad. Do not buy the G&G SUSAT. Oh my God, what a piece of over-priced rubbish. I could go on and on about the dreadful build quality, with the wiring that's a real mess, the base plate being 3D printed plastic that crumbles when you try to change the batteries, and the fact that the optical sight is misaligned to the left, no matter what you do to adjust it. The optical sight defies physics and it seems I'm not the only one that has had this issue. The iron sights are OK, but the rest of it is awful if you actually want to use it as a scope. I need to get around to getting rid of mine, but with a huge health warning that says it only good for a wall-hanger, and you should only use the iron sights if you want to hit something in a game. It's that bad and G&G should be ashamed of themselves. Part of me feels I'd be doing the Airsoft community a huge favour by burying it at my local site. Ironically the Chinese SUSAT clone I bought off Amazon for £20 less than the G&G one is really good. It actually magnifies properly and works as a scope, so that's a far better buy.
I'm not sure if any of that helps. They sometimes come up in sales, so you might be best waiting to get a bit of a discount.
