First impression was odd. the gun is so light I thought AA forgot to put something in. It's entirely made of plastic (even the 14mm CCW thread is, so be careful) but it feels toyish on one hand due to weight, but rock solid on the other, zero wobble.
Dry fired about 40 rounds just to check if it was working and oh boy, the recoil is minimal, even in full auto. Due to the tiny amount of moving parts and their weight, I expect it to be really efficient (50/60 rounds with a single gas fill).
Can't wait to properly test it on Saturday (or even Sunday if we play), if it performs it will replace my G17 (which will get a carbine kit as a compensation)
