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 trigger and high-heat contact switch, ball bearing spring guide, and steel gear set come pre-installed allowing for an easy, seamless drop-in installation.


  • Fully polished "Silver Edge" gearbox
  • Polycarbonate piston
  • Steel gear set
  • Ported cylinder
  • 8mm stainless steel ball bearings
  • Integrated "quick spring release" function for easy spring change
  • Reinforced Gearbox Shell
  • "Hybrid" electric blowback. Can be disabled
  • Wired to the rear with a Small Tamiya plug
Compatibility: For APS, Matrix and other compatible Ver.2 Gearbox Airsoft AEG Rifles (Comes with M4 / M16 style selector plate. Other style selector plates sold separately)
Gearbox Type: Ver 2, Full Metal
Motor: Long Type (Not included)

"This is a very high quality gearbox shell is similar in quality to shs Cnc Aluminium with quick change spring ebb but that can be modified piston and cylinder are not the best has the 8 mm German caged bearings not the ones shown in photo which is fine with me I think they are a stronger bearing anyway I completely scraped the internals when I got it I did have to machine the inside of the gearbox to fit a different set of gears pretty easy with a drimel and router guide tungsten carbide cutter bit similar to an end mill style the ebb feature is neat I kept the bolt cover but modified it to remove the ebb feature installed it in an aps comp receiver with working bolt catch that is a really nice feature for adjusting hop up I tried a standard upper and bolt catch lever worked on that as well would recommend aps receiver tho great gear box really impressed

"I bought this for my mp5 so I had to replace the trigger and selector. This thing run super smooth and relatively reliably, the piston and piston head are kinda junk (I would save on shipping and order one when you get the gearbox). Also the shell has special holes for the gears so you can't change the gear ratio.

Good shell
Good price
Very smooth (I shimmed mine a little)
Quick change spring
Good stock fps

Piston it plastic except for one tooth
Piston head is pretty cheap
Wiring isn't the best.

"Had a ton of trouble fitting into my CM16 raider shorty, but with some dremel work, and paired with 6.03 prommy barrel, prommy purple bucking, prommy bridge type nub and prowin hop up flat hopped, that gun turned into a real sleeper. I attribute alot of that to the good compression. Only chrono at 360fps, but that may be due in part to such a short barrel.
