"Received it with a broken air nozzle. Would seem that a "basic" inspection would be a good idea prior to shipping.

"The wires are not even the right length to fit into the stock, the clear part in the photo is under the gear box thats how short it , and it will not fit into the M249 body, its also not the same one in the photo.

Complete Gear Box Set for Echo1 A&K Classic Army M249 MK46 Series Airsoft AEG

Great for spare, replacement, upgrade and more! Having a spare gearbox is essentially having another gun! Pre-upgrad to shoot at 350~400 FPS. Great drop in ready to go gearbox. Spare shell and a spring guide is retailed for $85 alone. Great value offered directly from the origin of the best M249 series AEG out there. (Disclaimer: For experienced players only, due to that we cannot test complete gearboxes before shipping, it is recommended that buyers have gearbox knowledge.)

Complete gearbox includes:
-Gear Set
-Spring set
-Reinforced Cylinder / Piston set
-Metal Spring Guide.
-Switch Assembly
-All the screws
-All the wiring, tappet, and fuse.
-Reinforced Metal gearbox shell.

A great upgrade if you have a old version of the Classic Army M249! Newer design and better performance compare to older technology!
We have compiled a series of videos for AEG take down, assembly and gearbox for your reference. Recommended for experienced players only.
