Features

  • Factory direct complete OEM replacement gearbox
  • Built in MOSFET unit regulates battery current to protect the trigger contacts
  • Padded cylinder head helps soften and absorb some of the transferred shock
  • Reinforced piston to withstand the high cyclic rate of the Nautilus Gearbox
  • Easy spring change allows the spring to be swapped out without disassembly of the gearbox
The KRYTAC Nautilus reinforced 8mm ball bearing gearbox features an integrated MOSFET to regulate electronic signals and to protect the trigger contacts. The corners of the gearbox that surround the cylinder feature a smooth radius, as opposed to a 90 angle, to prevent fracture. Also, the gearbox shell features a small window on the left side where lubrication can be applied directly to the gears or piston, this window is also convenient for inspecting the angle of engagement with the gearbox fully assembled. Additional gearbox features include a modular spring guide system that will allow the spring to be changed without completely disassembling the gearbox.

The KRYTAC piston is made of a durable, lightweight polymer and features 4 metal teeth, with the 2nd to last tooth absent. The Cylinder head is padded with an enlarged rubber bumper to optimize the angle of engagement and to absorb energy form the impact of the piston assembly. The material for the gears have been especially formulated to be very strong, Rockwell test figures on the KRYTAC gears are much higher than industry norms. The spur gear features a tension system built into its axis to keep the gear perfectly aligned while under load.

Other features of the Nautilus gearbox include the anti-corrosive coating that give the gearbox it's unique color and the wire keep for the motor wires around the base of the gearbox. Each component on the KRYTAC Nautilus V2 Gearbox has been designed to perform at a high level and to be user friendly for the technician that repeatedly tunes their AEG. This is the standard gearbox for the KRYTAC Trident series of AEGs but it can also serve as a replacement or upgrade to other AEG platforms.

"Krytac gearboxes are awesome and easy to work on if you are looking for that Titan or Spectre upgrade.
Nice solid gearbox that is what I needed (which is another Krytac gearbox!)

"These gears are great, no need to change them ever, and no they are a lot better then just stock gears, and yes they are worth 75$ heck Should be more $$$ whoever thinks these gears are cheap or not god tier.... Your wrong. Best aeg, can compete with a polarstar or anything else in your field.

"This is a great gearbox! I can't stess how high quality MOST (foreshadowing) of the components in this gearbox are. Easily one the highest quality gearboxes on the market.

It is by far the most reinforced gearbox I've seen. I have a 45K rpm motor that snapped my previous fullmetal gearbox in half, but with this thing I have absolutely no worries. It's hard to convey how much extra reinforcement krytac added.
This gearbox also came with a padded cylinder head which is incredible and just adds the this beast's reliability.
It also comes with a nozzle that already has an O ring installed stock!
The bearings are 8mm and they feel super high quality.
The gears feel really nice and they even have a self shiming system which is just crazy!
The anti reverse latch is designed in a way that makes the gearbox easy to work on.

So there's a lot right with this gearbox, but here's what they got wrong.
This is minor, but I wish krytac would say what spring comes in this gearbox.
For such a high quality gearbox, I wish the piston had all metal teeth instead of just the last three. The plastic is not the strongest and I would recommend upgrading to a more durable piston, especially if you're wanting high FPS or RPS.
But easily the most disappointing part of the gearbox is the trigger unit. This gearbox really struggles of you run an 11.1v lipo. Which makes me beg the question, why make such a durable gearbox if you can't even put any real power through it. When hooked up to an 11.1v lipo, the gun will randomly overspin and then your gun is stuck in two round burst until it randomly switches back. This gets really annoying and for a $212 gearbox it's unacceptable in my opinion. After putting less than 1000 bbs through it, I upgraded to a mosfet that rhymes with Tate Ritan and there have been no issues whatsoever.

So after a new mosfet and an AOE correction this gun shoots amazing! It's an absolute beast! I would still recommend this gearbox. If you want a gearbox that can take a lot of abuse, buy this. Just know that you'll probably have to replace the trigger unit and the piston.

For those of you who hate reading...

Pros:
Insanely durable
Padded head
Nozzle fitted with an O ring
Gears are self shiming and super durable
8mm bearings
Wire cover to protect wires from motor
Easy to work on

Cons:
Don't tell you what spring comes in it
Doesn't come with a full metal teeth piston
Trigger unit can't even handle an 11.1
Randomly overspins on 11.1 causing two round burst
