Prometheus Sintered Alloy Metal Bearings for Version 6 Airsoft AEG Gearboxes

"Got these in my TM P90. The critical middle Bearing fits nice and snugly as does the bottom bearing, but I found that the top bearing VERY difficult to get in, on either side of the shell, and with any bearing. I was able to get them eventually but it took a bit of fitting. They are a bit thicker than other bearings (Stock, Guarder, ect), and I found I needed to do a total reshim; they stick into the inside of the shell a bit more, to the point where I found I didn't need a shim on one side of the Spur gear, and way more shims on one side of the sector gear than I have in the past.

Otherwise these are fantastic. They are sturdy as hell and I cannot see a time when I would need to replace them. The gears themselves will wear out far before they do.
