I'd recomend working on a clean paper background, no of course this Echo1 red&black .... shemagh(?) looks cool, but it makes harder to see small parts.

Nevertheless, this is a great video for all who wants to dig into tech of your airsoft gun.

Nice video. Good quality, and show's clearly how to disassemble the M4 Gearbox. Great video for those who don't yet know how to do it, and also those who want to know all the parts inside their guns.

Hey Echo1usa i recently purchased a stag 15 full metal m4 and when u open the dust cover you can sorta see the piston/ spring guide through a small hole ...but my question is it dosent look steel or metal? it looks like orange plastic or something..but i might be wrong... reply thx echo 1

Pleaseeee help!! My stag -15 full metal won't shoot, motors good, wiring is in tact, when I opened the gun up and got to the gearbox I slid the selector plate so that the copper would contact and it would fire. Nothing, what could be broken inside the trigger? Ps battery is fine and so is fuse.. Pleeassee help!

[MrDrAlfonso]

is everything in this gear box metal?

Where can i find a list of the parts and what they're made of for this specific gearbox. Some things I can figure out just by looking at them but I would like to know about every part in here so I know what to replace first.

umm im havin a problem wit ma new echo 1 m4a1 carbine. i'd been shootin it a couple of times & now it's not workin. i think i'd let go of the trigger a bit early & now it won't shoot. i tried wit auto but same result. it won't shoot.... there is no sound when i shoot which means it definitely does not shoot. i wud appreciate it if u answer back wit helpin ma problems.

[BAYCITYAIRSOFT]

Can you make a m4 tappet plate/selector plate/selector switch video? Can't seem to get my selector switch to move right.
