"So got this gun in a few days ago from Airsoft Megastore.
So far I've been very impressed, and for someone who upgrades KWA's that's saying a lot. Out of the box first impressions are, "man this thing is heavy". As usual I started by taking my screw driver kit and tightening everything on the gun, only a few loose screws and the whole gun is very sturdy for something this big. I feel Like i could drop it onto concrete and it would still shoot fairly well( Do not drop it on concrete). The gun does not come with a manual. However for anyone that knows how to use the internet this should not be a problem. So battery compartment is hard to get too, not the end of the world, you have to remove 6 screws from the heat cover and detach the barrel to properly place a battery in. however there is alot of space, shouldnt have trouble fitting any thing but the biggest batteries.
So shooting. Gun shoots smooth and consistent with .20 Game Face BBs from Walmart, (yes I know they say not to use them but I'm convinced the system is rigged. The recommended brand TSD is garbage, they jam in the mags and feel rough. I would not recommend. However most of the other recommended brands are very nice.) The stock hop up on this gun is trash, First thing you should buy with this gun is an upgrade bucking, I use a KWA 2gx Bucking and it nearly doubles the range. Gearbox is a Brick, Very nice very strong, I feel safe shooting this thing for extended periods with such a durable gearbox.
In conclusion. Get a new bucking, get a nice 2 point sling, and a 9.6 or 11.1 v Li-Po for a nice RoF. Great gun. Highly recommend."
