"I ordered this gun skeptically. I love G3's and Mp5's, but G3's are too long. This is exactly halfway. The power of the G3 with the length of an MP5. It comes with a Ni-Cd 8.4v battery, full metal scope mount, charger, and the gun. Metal parts on the gun include the stock mount, barrel, mag release, sights, magazine, and obviously the gearbox. The rest is high quality plastic. I was extremely surprised with the quality of the plastic. No wobble whatsoever. None. Very, very sturdy. The gun shoots incredibly accurately with the hop-up dialed in on a full battery. Around 350FPS, great for CQB and Field. Goes through a can from 70 feet. It shoots incredibly fast, around 900rpm with the stock battery. The magazine holds 500 rounds. I'm using Bio 20 grams and they work perfectly. All in all, this gun is an absolute beast."
