"Quick conclusion: After owning well over 20 different airsoft guns and teching for a while, this is one of the only new airsoft guns that I didnt really find any major flaws in out of the box - except for that the battery space is a bit narrow (but long at least) .

Gearbox: I dissassembled the gun on the first day I got it to inspect the internals. I was surprised to see a type 0 cylinder (no ports or holes) for the given barrel length. Typically those cylinders are used for longer barrels, but it should be fine, not that big of a deal. I used it for my rpk. The aoe was not correct, but its almost never correct out of the box for any new gun, so no worries, just cut the second tooth on the piston and add a sorbo or something to move the piston back. Gears were fine, compression was ok, has a metal bearing spring guide if I remember correctly. Metal bushings. Not a bad gearbox! Selector gear was plastic, so dont go ham on the selector switch.

Externals: Amazing! VFC style using pins. Mostly made of steel (checked with magnet), and plastic furniture feels like good quality. Stock is sturdy, hopup chamber is metal. Charging handle does sometimes catch on to the hopup adjustment, but I just grind down the hopup tab a bit so it doesnt touch it. Weight is perfect. Mag is plastic and lighter than my other 5.45 style mags (for ak74), but feeds actually quite well.

Try heavy bbs, it likes them better (at least .25s will do). Dont use .20s, they tend to either be overhopped or underhopped. Be cautious of the battery space, its long but narrow, barely fit my 7.4v lipo battery. Believe me, after changing my loadout a buch of times, out of all guns ive owned, the ak platform is the most practical - mags hold a ton of ammo, strong body that is durable, cheap compared to m4s, v3 gearbox which is more durable, and feels like a real gun in your hands. But buy whatever platform you like, the ak is just my favorite so far.Awesome rifle, definitely keeping it as a lender gun for friends!

"This was bought for my wife as her first AEG. Her first ever airsoft experience was a 40hr MILSIM WEST event. Surge on the Steeps. This AEG performed and ran hard all weekend on a single titan stick battery. The Titan battery only fits under the dust cover, not down the battery tube.
She used the CYMA clear mid cap Bulgarian mags.
You have to watch the hop up adjustment. After you adjust it and close the gun it can push it all the way forward.

"Absolutely love this gun. It's very solid, my first game out with this AK and I took a fall face first causing me to fling my rifle a good 5 feet, ran over to it and picked it up. Nothing broke or even scratched. Along with the rifle made decent it feels fantastic, the folding stock is easy to fold and stays in place once locked into place. I'm very happy with this purchase.

Now, with that being said onto the things I don't like about the gun. One thing I have noticed about this rifle is that the battery is wired via the top where the dust cover is, sometimes when the battery is in and the dust cover is on and you slide the charging handle back to adjust your hop-up and then you slide the charging handle forward there's a good chance it'll mess up your hop up. It's an extremely tight fit with the battery. I'm using a 8.4 stick type, unsure of how other battery's will affect this. Another thing that happened to me is that the magazine it came with stopped working after a little, when winding the magazine it doesn't load the BB's into the gun at all. Oh and the fake cleaning rod it came with is a little annoying in my opinion so I took it off when I noticed it.

So long story short:

1. Gun is made reliably.
2. Gun feels solid, doesn't feel cheap and you can tell it's made with metal.
3. Nothing with my gun was loose, shaky, or non-sturdy.

1. With a battery in the rifle, dust cover on, and you go to change your hop up the charging handle may mess with the hop up when being pushed forward.
2. The magazine the rifle came with ended up not working after a little however I managed to get 3-4 days worth of games with it before it stopped working.
3. Cleaning rod in the gun is annoyed. (Could or could not be a con for you however I don't enjoy it.)
