If your also looking at videos of the takedown of guns and gearboxes try www.mechbox.com and look at the m733 disassembly as well as the v2 disaasembly. I only suggest these videos since it would show the parts in a gearbox and also basic breakdown procedures even if it is a TM product.

Also I know you didn't say you wanted an ICS MP5 but they do not have the spring swap feature. They are working on it to do that but as of right now it is not avalible.

KWA's have possibly the best internals stock, are reliable guns and very sexxxxxxy.

i own one, gamed it many many many many many many many times. simply wont break.

parts are 99% interchangable with other legit brand m4's.

ICS isnt bad. KWA eats it and shits it out lolz

Sweet!! I learned about all the internals in my 1911 using a short video on Youtube made by some regular user, so some pros taking down some AEG's should teach me a lot!! :D Much appreciated, I'll check out the site soon. :))

Are the gearboxes in those guns similar to the M4's or does it not really matter too much about small differences? Either way I'll check them out, I'm just wondering. :)

Nice man, thanks for the info on the MP5 anyway, it's good to know. I'm absorbing all this. :D

Oh thank God I didn't order that KWA. O_O

I love you Airsoft Canada. :D Thanks for the info man, I wouldn't want to interchange the parts with non-legit brands anyway so this gun is really sounding like it should do the trick. ;)
