Full metal except for the parts that aren't suppose to be. This is a really nice weapon. My chronod at 400 when shipped. Once zeroed this gun shoots very accurately thanks to the already installed tight bore barrel. I've had no wobble anywhere, but expect that the stock may loosen up with use. The dust cover doesn't like to stay closed, but that isn't that important to me. I used this last week in during my team skirmish and I was hitting people clear across the field and that's before I zeroed it. I would recommend using a large type battery since my mini 9.6v 2200 mah battery cause the gearbox to lock once it started to weaken. My mini lipo made it shoot better but drained quickly due to the type of gearbox and internals.
Working bolt stop
Charging handle pulls the bolt all the way back
High FPS out of the box (400)
Included front sling swivel adapter (good for a harris style bipod)
3 RIS covers included
Mock Silencer included
Takes large type batteries
Dust cover doesn't stay close (not that important)
May lockup when the battery you're using weakens.
The orange tip is on the mock surpressor and barrel.
