||I got this gun just recently, and I love it.
The shotgun is actually durable, despite being plastic, unless you're dumb with it and whack people with it or something. It also comes with a rail, so if you want an optic on it you can go ahead and put it on. I have an red dot on mine, because I don't like aiming down the sights.
The sights are okay, and are adjustable via Allen key, but they tend to be a little hard to aim down if you have a metal mesh mask like I do. But it's a shotgun, who needs sights? The pump is very hard to pull back at first, but once you get a feel for it you could shoot the whole shell in 5 seconds. The shell holds 30 BBs, and is okay I guess, I don't see much wrong with it. Remember, the gun shoots 3 round burst so that means 10 rounds per shell. The shells can be refiled with a speed loader.
One BIG thing, if within a day or so of shooting the stock and pistol grip gets really loose, it can be fixed easily. Just remove the stock, like you would an M4 or something, and get a long, big Allen key and screw in a screw that keeps it all in place. If you tighten it, you wont have that problem for a while.
Stock is adjustable and easy to adjust
3 round burst
Came with a sling which was pretty cool
Wobbly stock and grip at first, until you tighten
Virtually only 10 shots per shell, but shells are pretty cheap
Pump requires Schwarzenegger-tier strength the first couple of times until you get a feel for it
