Great gun, bought it here. the rails are solid. stock is solid. first mistake i had made with it was that i pulled on the fake charging handle to far while disassembling the gun. was a great gun for CQB and effective range is great for field work. the gun was very quiet which allowed for greater stealth in CQB operation. the Motor overheated after using the gun on full auto for 1 minute. the style of picatiny rails didn't allow for the greatest stability with some attachments especially a G&G made vertical grip. going to work on upgrading this gun in the future. used it for 1 year
good starting FPS for CQB, 330fps (out of the box)
simple to take apart.
Very light weight
motor overheating after 1 min of full auto fire.
Picatiny rails aren't the worst but they can't secure the same company's VG. if the attachment point of the VG was different it would be more secure.
out of the box it was 330 fps when i was expecting 350-370fps.
reduction of fps over a couple of months (it is one year later and now it is 220 fps)
