I've disassembled and reassembled Dboys guns over and over, screws stripping is a myth. If you use the wrong sized screw driver head and force it then you'll strip it. If you take your time to choose the right sized head and take your time with threading your screws won't degrade if you take it apart multiple times. And another thing shimming and bushings on my MK12 Mod 0 is still stock and I'm running an M120S thats pulling 390FPS.
The metal body, I'd have to say it beats the metal body I got made by CA since the CA one uses two crappy pins whereas Dboys uses a wide lip at the end.
