"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 ;)

"This gun has the lightest metal receiver amount the China made metal receiver(compare to metal receiver made by D Boys or AGM).The whole gun minus the magazine is only about 5 lbs which will not slow you down in long outdoor games.Good base gun for upgrade because of its 420mm inner barrel potential.Very solid and no wobble.High 400+ FPS ;High rate of fire with upgraded battery.

"i didn't buy this from evike i got it shipped from china about a month ago. its a very nicely made gun. although the first thing i did was re-shim it (because the gears where wobbling) and lower the spring to a guarder sp100. The barrel it comes with is a standard length m4 barrel (357 mm) and its doesn't go to the tip of the barrel. what you should do is buy a 420mm barrel to cover the length difference. 420 is the correct length. The barrel also is very hard to get in and out. you have to undo the whole front end of the gun. it comes with metal bushing and a metal spring guide with a bearing (shoddy bearing). also don't get an aftermarket air nozzle alone. it wont fit due to the

WARNING it DID NOT work with mag midcaps!!

"This gun looks pretty awesome. I'm either getting this, or the JG Sig Sauer 552 Commando. If anyone knows about both of the guns really well, can they tell me which would be better? Thanks!

"Mine chronoed 400 w/ .25s, around 440 w/.2s. Battery is not sufficient for a good rate of fire, but will fit any mini battery or nun-chuck, I am running it with an 11.1v 1100 mah lipo, which fits fine.

The inner barrel is much shorter than the outer barrel, there is at least 10cm of extra room to extend it. The cylinder is a full cylinder, so you won't have to worry about air volume issues. The longest barrel that will fit in the body is 420mm.

The handguard will wobble very slightly unless you screw one of the provided sling mount attatch points into it, which must be unscrewed every time you change the battery. Aside from this changing the battery is v. v. easy, much easier than a standard m4a1 - the foregrip slides forward, put batt in place, slide it back down. Looks small on the website, but there is tons of space inside.

Body feels fine, gun is fairly light which is a plus. The finish on the body looks good, but feels slightly more dry and less smooth than on some other metal bodies, for example G&P. The paint on it scratches easily.

The handgrip feels good.

The iron-sight being placed forward makes it a lot faster to use, I might actually use it on this gun, rather than replacing it. Sights don't wobble, etc.

Stock does not wobble at all, locks in place well and feels v. sturdy.

The included flashhider is pretty sexy.
