"Got this after battling an ASG AUG A3, a P90, and an MP5. Decided mainstream is the way to go. Functionality is gorgeous, it runs like a dream. The stock mag is a flash mag and a little loud but feeds fine. I personally have a high purchase on M4 grips so I filed and sanded a little of the grip corners for comfort. I made sure to tighten up the little screw on the stock. Also as a side note, the flash hider is METAL and very hard to remove to use a blowtorch for about 2 minutes to soften up the glue then take it off. Paint removal is up to you. I am not responsible for anyone's actions. Be safe.

PROS:functionality is peak
Light even for a metal gun
Comes with magpul clone slip-up sights
QC spring
Trigger response is crisp
Keymod rail system
One piece hopup/barrel

CONS:wobbly stock flash mag (other mags are fine and this mag functions fine too so not really a complaint)
Stock is eh
Flash hider has some strong glue
When disassembling the "bolt" may spring out

And that's it! It was a good purchase for me so I'm happy

(An XCortech mini tracer fits absolutely perfectly with the hand guard:)
