It’s a 2014 parts kit put together. Etiny electronics as far as I can tell. Has KUMI 490 motor with a systema gearbox. One of the ears on the trigger guard has been glued back together. Upper and lower wobbles without a little velcro inbetween. Not too big of a deal. Gun currently works and works quite well. I test shot two mags through the gun. The pmags fit and feed OK with a little bit of Velcro in the magwell. Comes with one cylinder. No holosun. I can include mags aswell for the right price. none of the mags are currently great at feeding. This is likely a mag spring issue. Obo
