Yeah, it does. I tested between the bore-up kit and a regular kit and saw no difference in velocity, consistency or rate of fire. But at the time, I was testing with a Systema M120S. I think that since that spring is the minimum spring recommended to start using a bore-up kit, and 590mm is also the longest inner barrel you can use with a full normal bore cylinder, the performance of the two setups overlapped at that point.

I'm saying that because I'd love to get that one gearbox where you rarely worry about it no matter the cost.

I never said that Pro-Win isn't the best there is. In fact, I think it's the best at what it does. It comes down to what qualities you consider to be "the best." If you're looking for a gearbox that you can easily install, then no, Pro-Win is not the best. It's probably the worst in that regards. But if that factor is something you hold high, then just get a Systema drop-in gearbox. Don't even have to open it up and worry about shimming.
But that wasn't the point of this project. The point was to get the BEST full-featured performance out of this gun platform.
I still think the Pro-Win detachable gearbox is the best gearbox you can get for a standard Marui (clone) AEG because of all the added features it provides on top of the added durability.
Does it have issues? Yes, it does. Installation is difficult and skill is required.
The gearbox has always been marketed with a very clear warning:
"INSTALLATION TO BE DONE BY PROFESSIONAL ONLY."
I concur with that statement - if you're adverse to performing hard modifications, STAY AWAY from this gearbox. If the idea of grinding up your brand new metal receiver scares you, STAY AWAY. This is what I would consider to be an advanced installation.
But once this gearbox is installed properly from the beginning, it will provide for you an extremely solid and well performing platform.
