What I'm actually looking for is someone who can assemble a chinese parts set on a 1.6mm receiver with the proper rivets etc. I like the robustness of the 1.6mm guns and the chinese parts, but I understand they may be a little different to assemble. I checked out Rifle Dynamics - $400 is their base price for assembly - that seems steep, if I'm supplying the receiver and parts. I was hoping to be able to build one cheaper than simply buying one. Plus, I can chose how I want to finish the receiver - blued would be my preference.
