At first time, my original plan was using the plastic gearbox for boys(age of 14 or older).
but in korea, the power of the airgun's regulatory is only 0.14J!..(in other word, that is very very weak. never hurt even hit on the face.)
you can't guess that how is it so weak. to tell the truth, it can't make any holes or even scratches on the box!

Do you want know about fire range? just awesome.
Bullets doesn't fly 10 meters out. that is the limit. so funny right? how to targeting with this?

Fire rate? that's also fantastic.
It can fire 4 bullets per second(240/min) with full automatic fire.
maybe you'll 'hey, I think that is not so slow :P'..
well..If you do so, then see this video



Tokyo MARUI M4 CQBR EBB(Electric Blow Back)

Although, that is for adult, and very expensive(almost same price the new computer.) but look at the fire rate.. it's almost 17/s!

In conclusion, I want to say is, 'Korea's Airsoftgun is just a shit!'
So?.. I remove it and throw it away from the project.(IDIOT GEARBOX! GET LOST!)

And then I find something very profit for this poor gun..



this was my M4A1 AEG(Airsoft Electric Gun).

As you can see, the upper body was.. broken.. Sadly..
But fortunately, I have a barrel of it, no problem on gearbox, and the problem is just only upper body's connection link is broken.
And also, as you can see, that gearbox is consists of metals. and version is for adult!(As an aside, I upgrade it before such as motor, piston, mainspring, etc.. so it have a quite high performance.)


So, I'll make this gearbox can be ported on this gun
In other word, I changed the plan! that's all!
comming soon at June or July!
(M4A1 lower body with LFG-2000 upper body.. wow..what a nice combination XD)

P.S. sorry for my stupid monolog. I promise that I'll be back with much more developed gun next time!
