It's really solid for the price. Made out of actual steel and it feel different than the rentals you usually see.
It has a quick change spring and I like the grip of the product. The internals are actually an upgrade compared to older generations of Double Bell. The company really upped their game with installing decent gears and air nozzle. The only thing I dislike about it is that the barrel of the gun is not that tight when you move it with an attached vertical foregrip and they really reserved the least amount of lube for the internals (easily fixed by yourself).

Overall, would recommend to a newbie in airsoft!
