I recently purchased this item and all I can say is WOW! Trade marks are perfect and it shoots great. Im using a 7.4v and it gets around 800 rounds a minute. The only issues i have is that the charging handle is very stiff but it will eventually break in over time. Also the mag release gets caught when you press it to release the mag. All in all buy if you can.
-large buffer tube for battery
-Mag release gets caught
-Charging handle is tough to pull back
