Excellent quality gun, shot 450 fps when I first used it, after 3k rounds it fired about 415. The body is alright, the black paint comes off easily (expect it to get scratched), and I had no trouble smashing chunks out of it with a screwdriver and a hammer (was fitting a pro-win box in it). I don't believe the body will break in regular play. The stock got a bit loose but was fine after I tightened the screw.

You should be aware the inner barrel is shorter than the outer barrel, and though I didn't try it, I believe it will lead to poor accuracy (it looks pretty shitty). The barrel length is 420mm and you should replace the barrel as you buy the gun. The hop-up unit is fine.

Inside the gearbox there was perfect seal. The bushings were rather loose in the shell and the gears mostly unshimmed, but it is unlikely to cause any problems, it sounds smooth as well.

ROF with the included 9.6v 1100 NiMH is lower than, say, a stock TM but about what you'd expect for over 400 fps.

The gun comes with an AR stock-tube retention ring tightening tool, useful item for a lot of guns - not sure what to use it for here, given the LR300 stock is attached entirely by a screw :p

The included magazine is fine and feeds well.

I ran the stock gearbox for 3000 rounds on lipo with a systema magnum, and did not notice any damage when I inspected it afterwards.

The gun is also really light, which is for me a bonus, but some airsofters like to punish themselves ;)
