"If you are in the mood to scare everyone on the opposing team... GET THIS! The tight bore barrel is amazing. I am shooting harder and farther than anyone on the field. My only complaint is some slight structural issues, but that might just be my OCD. Overall this is amazing. The build quality is great. You may be thinking, "Great another stupid M4." That my friend is where you're wrong. Are you ready to bring the pain? BUY THIS GUN!
PROS: High RPM motor, extremely hard hitting (mine was almost maxing at 487 fps!), Solid and heavy gun (you may want a sling for it), Everything you think would be plastic is metal, great mounting space, adjustable sight, removable sight to replace with optics, metal sling handles, tight bore barrel (6.01mm), You could almost snipe with this gun, loud and a tiny bit of kick for a more realistic feel, where polymers are used they are used reasonably and are very sturdy, bolt catch to adjust hop up, could take a lipo but might need some slight upgrades to maintain it for a longer time if used consistently but I am not sure if you really would need upgrades it is a reinforced gear box.
CONS: Stock can feel a little too shaky at times, Burns through a 300 round mag in about 30 seconds or less (this may be good or bad lmao), some structural issues with the receiver the upper and lower part aren't quite tight enough together (this may be fixable with some tightening i just don't know
Overall not any huge problems just small ones that you won't even notice when you are destroying the other team.
Just a little side note, I had a night match and when people turned their flash lights on while shooting, you could see spaces between the bbs being shot... when i turned my flashlight on and shot in full auto it looked like a constant beam of bbs it was shooting so fast it looked like a laser.
one more thing the hop up is perfectly adjustable to your sights... you can aim down the sights and actually hit something. Great gun enjoy it!"
