KRYTAC Complete 8mm Nautilus Version 2 Gearbox for Krytac Series Airsoft AEG Rifles

"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.
