||this is a beautiful gun, and a beautiful deal.
i like to read reviews and research before i buy anything, here is what i have to say:
1st off go to airsoftreports.com and look at the video reviews for this gun.
they give an expertly done video review.
2nd off i have no magazine wobble as listed in the previous review.
my magazine works very well and is sturdy as can be.
in the ar video review they mention that the single fire mode wont click in.
i believe that may have been either the individual gun the recieved or lack of knowledge on their part.
its kind of tricky, but it is very a definite feeling when switching firing modes.
the gun clocks in at 335 fps average. thats 10 fps more than it claims, showing some humility on jg's part.
the stock has multiple [five - 5] levels of adjustment, making it a well adpating gun.
the sight also adjusts to four  different distance ratings, all of which are base on personal preferance.
the hop-up switch is easy to use in the middle of any airsoft battle, and works well.
the gun has an affective range of over 150 feet with very good accuracy grouping.
the fully automatic or rapid fire mode has a very good rate of fire.
the magazine that comes with is indeed a high-capacity 200 round mag with a crank wheel that is very wide and user friendly.
my friends with other jing-gong and echo 1 magazines agree that the mp5 wheel is the most prized.
the gaudy flash hider comes off to reveal a very appealing and still orange tipped [for legal purposes] muzzle.
the mock cocking lever is said to be very fragile in other reviews, but mine is still in beautiful condition.
all you have to do is respect it and it shouldnt break on you. btw - it serves no real purpose other than replication/aesthetic appeal.
it has two comfotable magazine releases, the average lever release as well as a pistol-style release that only requires one finger.
it is an amazingly accurate likeness to the real sub machine gun.
the battery is not a stick battery [which is a common misconception].
it actually goes inside the handguard, which is rather comfortable compared to other aegs.
it requires a speedloader to effectively use the stock hi-cap magazine.
it does not come with one, nor does it come with a bb charger and charger rod.
[it does come with a battery charger, please do not confuse this with a bb charger]
with any aeg you should do two things.
a. after firing in full-auto make sure to shoot one semi-auto shot to decompress the spring inside.
b. discharge the battery for further battery life, to do so buy a battery charger.
all in all this is a 5/5 star gun, especially for one hundred and five dollars [$105].
