- 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.Version:

"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.
"I have mixed feelings about this gearbox. Krytac says they want their line of guns to be as non proprietary as possible so most of 3rd party parts could fit in their gearbox. It's only Logical especially in a world where upgrade parts are endless. A non proprietary gearbox sounds amazing. But for the Krytac, its true to a certain extent.
First off all of the internals are high quality and can last you a long long time. With a heavily reinforced gearbox that'll take earthquakes to destroy, comes neat features such as the built in MOSFET, locking bolt catch for easy hop up dialing, wiring reinforced with tons of shrink wrap, easy spring swap system and tons more features. Everything runs as smooth as water in this gearbox.
Now the gears, this is where things get extremely disappointing. The gears themselves are fine. In fact, better than most stock gears with a self shimming feature....that are worth $75 that are PROPRIETARY to the Krytac gearbox. Yup. Therfor you cannot not replace them with any other gears other than the $75 gears Krytac sell.
Let me tell you. These gears are definitely not worth $75 dollars. You can get true CNC steel high grade gears for nearly 1/3 of the price that will probably last you longer. But lets say you do buy new gears and replace the Krytac sector gear. Your result? The gearbox will have a gap unable to form a full parallel seal. But let's say you still try to screw it down. Not only will you ruin your new gears you bought, you will also ruin the structure integrity of the Gearbox.
Bottom line don't try it unless you're willing to buy a brand new Krytac Gearbox.
A cheap move from Krytac forcing customers who bought their guns to purchase overpriced replacements parts that are proprietary to the gearbox the sell.
Again, the gearbox is a working horse that'll outperform most gearboxes out on the market. And for the price of a Krytac aeg, it is worth every penny. However, prepare to be a victim of cheap business when it comes to upgrading your Krytac.
"The gear box was great. Snappy trigger response and very nice build quality. The only bad thing is that It didn't fit in my G&G body so your going to have to find the medal krytac body which is impossible to find. Other then that its great!
