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.

  • Steel gear set

"I bought this gearbox because my a&key masada gearbox after I upgrade with something more powerful explose inside so this one was strong and the triger was awesome.

"UPDATE so i buy another silver edge gearbox and when i first saw it i noticed that i doesnt had the 8mm ball bearings just normals, so it might be a refurbished gearbox(come on EVIKE) . Well i installed it again in my mk12 dboys, with magnum motor and 9.6 v battery. I use it every sunday for two months. Then appears problems, the gearbox got locked up, i unlocked and then got locked up every time... next week i doesnt shoot anymore so i open the gearbox and... the spur gear has missing three teeths, the piston was damaged it doesnt work anymore. So im going too give one star.

"I have had this gearbox for about two weeks now and have only really used a few times. I opened it up and shimmed it and corrected aoe(w/ scatter plot sorbo), cleaned and re greased during the process. I am no pro but I followed guides and videos very well and everything looked great. Reassembled gun and sounded great. After one good day shooting, the piston pick up tooth stripped while doing one long auto bust(probably 20 secs). I was only using a 9.6 nimh.

The piston teeth, and piston head for that matter, are very basic and weak.
Also the cylinder head is plastic w/ a single o ring.

I am sure the gears are good enough for a standard set up like mine but as others stated, high rps or more than a 130 spring and they're gonna break.

8mm bearings should be standard anyway.

The compression was very good once you lube it up. O ring, metal air nozel is nice.

Overall I really like it. And for the price its awesome. I disabled the ebb and did some simple mods and it sounded awesome. Just gonna have to get a descent piston and see what happens from there.
