"I got exactly what I wanted for the price. The externals are very nice.The internals are decent, the gear shell is reinforced at the front corners and radius cut. It does not have a quick change spring and it had some compression issues. I changed the cilinder head, nozzle, put a new o ring on the piston and shimmed the gears, now its shooting 360 fps with .25 gram. This gun was 100% usable out of box shooting around 400 with .20 gram and was decently shimmed.
Good out of box
Great upgraded

"Great gun
Pros: great FPS out of box, mine shot 418 with .20 bbs, full metal, good weight, durable.
Cons: the pull back rod that opens up the hop up is utterly garbage. Mine got stuck the second I pulled it back but it’s a easy fix, the mag release is a bit iffy but some tape should do the trick.
Overall this is a great gun for beginners and even seasoned airsoft veterans. It’s great to start a DMR build on and is very accurate. I would recommend.

"this is sturdy and nice though my only nit pick is that mags i got fit, but it feels like im forcing it which im sure is fine, but it feels off overall good
