Your cart is empty. APS went the extra mile with their "Silver Edge" gearbox. They took their Hyrbid blowback gearbox shell and fully polished it internally, effectively reducing friction on the piston and other parts that directly contact the gearbox surface. 8mm stainless ball bearings, an extremely smooth trig and high-heat contact switch, ball bearing system, and steel gear set come pre-installed allowing for an easy, seamless drop-in installation.
Compatibility: For APS, Matrix and other compatible Ver.2 Gearbox Airsoft AEGs (Comes with M4-Style style mode changer plate. Other style internals sold separately)
Gearbox Type: Ver 2, Metal
Motor: Long Type (Not included)
Manufacturer: APS

Was a nice upgrade for my stock m4 - the upper receiver doesn’t like to fix super well and had to shorten the wires to the motor but besides that is great

The package was a little damaged. But the gearbox seems to misfire every few shots.

Used this gearbox as a drop in replacement for my lancer tactical gen 2 rifle. Has been working fine through several battles. Had to remove the supplied inline fuse for battery space and has been working flawlessly on 11.1 lipo batteries.

Used it on my son m4. Matrix full metal reciever and upper. It doesn't fit perfectly, had to file down a bit to fit. Also, had to remove the blow back for it to fit. Cannot use blow back. Works good. Installed mosfet with it to prolong the life of the trigger contacts. It has a sturdy and robust frame. Will take a beating with upgraded springs.
