I demoed the SRC version on sunday.
For the price, it really is quite good, and very hefty at that.
The model I tried's mock bolt kept getting stuck open when I tried to access the hopup, but that is my only complaint.
The ROF was good.
The gun made a nice sound, and I equate that to a good quality gearbox. (Although that is probably completely wrong)
The FPS was a tad hot, but thats an easy fix.
God is a /b/tard.
