Product Information:
The gun is made of a plastic (Polymer or abs plastic not really sure), strong construction with a 1 piece barrel, easy to disassemble and reassemble, the original battery is quite bulky for the small handguard i would recommend any type of butterfly battery except for of course LiPo, it is not lipo ready at all. Gearbox cannot be changed because the magazine catch will not fully come out of the lower receiver, when used in the field though it will be out preformed stock out of the box. I think it has a 6.04 inner barrel, I would say a new barrel would definitely make it a lot better but that's really all you could do to it since you can't get the magazine catch out, unless you drilled it or filed down the catch to the point it could slip out, it's also quite shotty on trigger response when trying to fire rapidly it will sometimes misfire, double feed, and the gears will slip and sometimes and be weird, it also sounds like it is about to die when in semi automatic, full automatic sounds very lively. And doesn't work very well with plastic magazines I bought some G&P metal mud caps which work flawlessly with this gun. The picatinny rail also is separate from the upper receiver and on mine it came off on the back end still screwed in by the front though of the rail and the orange flash hider can be quite revealing but can only be taken off with a very very very small Allen key. You essentially just get your money's worth for this gun, but definitely better options out there. (Would also like to point out I am no expert, in fact I'm a beginner myself, but I was putting my perspective and how it performed on the field stock and how it is off the field when adding new internals it's design could really use some work) I would also like to say that I am going to one day hang this gun on a wall in a frame though because it was my first Airsoft rifle and I'll hang it with my Elite Force M1911

Has metal in all the right places (except lower and upper receiver)
Looks metallic
Good for beginner players on a budget
Cool working bolt catch (can get jammed sometimes 2 ways to fix this give it a slap on the upper receiver you'll hear a click then press the bolt catch and it'll send the bolt forward, the other way to do this is just pull back on the charging handle a second time faster and let it go and then press the bolt catch and it'll send the bolt forward as well)
Easy to take apart and put back together
Comfortable in the hand
Bolt looks almost authentic like the real thing from Colt

Made of plastic
Double feeds when in a fast paced fire fight
Isn't accurate (stock out of the box)
Gears slip
Original battery doesn't fit well
Orange flash hider is revealing
M1913 Picatinny rail comes off every so often
When running the sling swivel can be annoying as it taps on the bottom of the outer barrel (nothing huge but can be annoying after a while just put on a sling will solve this problem)

Product Information:
I purchased this M4 a couple of months ago and I have had some time to really get to use this gun. I've been running a 9.6v butterfly shooting .28g bbs and let me tell you what, wreckage is an understatement. This guns outstanding fps and accuracy really allows you to reach out and touch someone and quite a distance. I can only imagine what a tight bore could do to it. Bang for bang and dollar for dollar this is the best airsoft purchase I have mad thus far.

- Price is great
- chronoed at 392 fps with .20g
- extremely accurate and reliable
- solid build, comfortable feel with adjustable stock

- Flash hider is glued and a really small allen wrench is needed to get it off (only a minor con)
- the feel is a little too much like plastic, although it makes it lighter and easier to maneuver around with
- lack of rail system other than for optics

Great gun light weight longer barrel for improved accuracy . ComFes with carry handle . Looks and feels real i added a long compensator to mine . The retractable stalk is worth the $$ with a metal gearbox durability is trusted to steel gears over plastic added a modified modified dual sector gear for double the bb output so insted of 600 rounds per second the G4 now fires at 1250 rounds per second . Added a red dot scope and iron sights also as of this writing ive had.the gun for 2 months now and shot 12,000 bbs thru it and no jams at all smooth gun buy one you wont regret it. I like to write about tunhe long run of a gun not when you first unbox it , its new so i shoot12,000 rounds thru then do a review.

Light weight
Good fps 400
Real looking
Durable plastics

Product Information:
This thing is skirmish ready right out of the box. The level of detail to the real thing is what amazed me the most. This was a great buy. I'm glad I chose this JG A.E.G as my first airsoft gun. It's sturdy. It doesn't feel like it will break in your hands. It functions smoothly. I'm new to airsoft, so I couldn't give you a comparison, but I was surprised on how smoothly it fired. At the price, I think I made a wise choice at my first airsoft gun.

-Very realistic feel. I carried the real thing in the Army for 6yrs and I can say, the weight and overall feel is very realistic.
-Metal Parts. The barrel, front sight post, sling swivels, hi cap mag, rail mount, removable carrying handle, buffer tube, internals are all metal.
-Plastic parts don't feel "cheap". Even the plastic parts are strong and sturdy. Unless you tap on the upper and lower reciver, I swear, you'd think it was metal.

-Iron sights are made of plastic. The rear sight on mine wasn't flush with the base and had a lot of free movement.
-The battery is difficult to store. The battery goes in the foregrip just under the barrel . I found it difficult to close with the battery and all the wires. I can't imagine trying to change one out in the middle of a skirmish.
-The trigger is plastic. This bothers me for some reason. I would expect one of the most moveable parts to be metal. It has a bunch of metal parts, why couldn't the trigger be metal?
