This thing looks like a gun, and sounds like a gun. It is used for military and tactical training. Has a wicked sound when shot. I have only broken a ball ONE time using this gun, but it was cracked before it was shot, so I dont really count it. There is no overhead hopper to get in your way, so you can add a scope, or a m-16 type carrying handle. At first it seems that you cant upgrade this gun much, but that is incorrect, I have seen wicked mods that can be done
If you want a gun you can abuse and not maintain, this is not the gun for you. It is a precision instrument, and can easily be messed up. Not a good cold weather gun if using CO2 (but what CO2 gun is?) You have to get to know this gun before you feel confident using it. The sound is louder than usual guns, which some might consider bad. If you dont use a hopper, you have to tilt the gun back to fill the magazine, (I find this an annoyance when in full auto because this thing can go empty in seconds :)
another bugger for me was the price was sort of steep (but worth it)
I LOVE this gun, it is well designed and you will have no problems if you familiarize yourself with its operation. It is not necessary to upgrade anything because the original parts are well designed and they cause no real problems. Parts are expensive for this one, and only a few places have parts. If your gun needs fixing you'll most likely have to send it in to ATS. Overall the gun is worth every cent I paid for it. This gun will outpreform most others if you take care of it. There is no other gun that even looks as cool as this one either.
