"I thought WE GBBRs were pretty bad until I got this one. They're actually quite good if you know what you're doing and are willing to learn. A lot of the parts inside are aluminum and they will break one way or another so if you want a good reliable gun that won't break for years, get RA-TECH Steel trigger assembly and Bolt Carrier. Don't buy the aluminum nozzle because the nozzle is supposed to be the one taking the beating and not the one doing it. Just get the Angel Custom reinforced polycarbonate one and you're good as long as you take care of the gun.

If you just want to keep it stock then it's still fine for 15-20k shots. If you're using a speedloader remove two bbs from the mag because that will break your nozzle.

10/10 awesome gun for people who like to tinker.
by Aroman F. on 04/05/2019
"This is my first gbb and it’s awesome I got 400-350 FPS out of the box but I think I may have been using .25g bbs haven’t had it for very long but I’ve put at least 200 rounds through it and it still works fine. One of my favorite features and this maybe cause I’m new to gas is it comes apart and works just like the real thing I was blown away by that

"Great feel and performance out of the box. For my rifle I decided to add a Magpul angle grip, Moe stock, xtm rail panels and a k grip with a real steel eotech. I took it out to the local field and it performed great until the nozzle blew out. GET THE RA TECH ALUMINUM NOZZLE.
With that said here are some overall pros and cons

decent finish
Moderate gas consumption
Mil spec buffer tube
Minimal magazine wobble
Lots of rail space

Plastic nozzle will break within a few mags
Pin in the barrel extension means you have to drill it out
You don't have this beast
