Honestly. I would not even go near those "high-end" TSD SRC guns. SRC guns are plain shit and the wiring is complete trash. OOOOO full metal body kit? Who gives? It's just to make it seem highend. The internals are "compatible" but you'd probably end up replacing everything after a few thousand rounds.
The SRC M4 blow'ed chucks. Untill I read some proper reviews then I would consider buying a SRC/TSD gun.
The Gbb's look promising but the AEGs... I'd stick to reputiable brands.
BuyAirsoft.ca seems to be alright, I've visited they're page often and it seems like they're stock comes and goes. So they must have customers buying from them!
Trixta let us know how your new V2 M4 goes. I'm eager to see the quality/performance of it. Hopefully they addressed the SEVERAL problems that they had in the v1 M4.
That Socom M14 is made by WELL not TSD. Hope that goes well for you.
I'm not bias about guns made from china, it's just that the damn QC is so bad.
