KWA

KWA makes the best AEG's and GBB's, in my opinion. All of their products are "engineered to outperform", as KWA says.

Their 2GX gearbox is amazing! I own a KWA CQR, KWA H&K Licensed G36C, and a KWA H&K Licensed USP. KWA's internals and externals are amazing. They're basically pre-upgraded gun; so good that law enforcement and military organizations use them for training. You just don't beat KWA.

Oh, and the fact that KWA AEG's are LiPo ready right out of the box is also a HUGE plus.
