Well then ol' chap, what about the bearinged stuff? I dearly wish to know also.

So wait (sorry, confused NOOB here) are metal bushings the sleeve type, or do they actually run some sort of a ball bearing through the channel?

I am gathering from the tone of the conversation that using metal bushings is considered an entry level upgrade for any gun with nylon bushings, but only if the spring is kept under M120. The bushings reduce resistance so much, and increase ROF so severely, that all you would need is a 9.6v battery on top of the mix to strip out the gears and piston (the next items in line in the "Wear-Chain"..) from the new tweaked out AEG.

Am I interpreting this correctly?

Thanks.

Bushings are solid metal.

Bearings (or Bearing Bushings) have ball bearing units. The 6mm Bearings may fail under an M120~esque load. The 7mm bearings will hold up just fine.

I've had problems with AREA 1000 pistons and Gaurder pistons. I'm aware that quality can vary from batch to batch and that different brands of gears can affect how long teeth on the piston will keep from stripping. There's a load of stuff that affects pistons...temperature, design, chemicals involved, etc.

Would I buy Gaurder or Systema pistons again, yes. Do I use them now, yes. Do I have a favorite piston that hasn't crapped out on me yet, yes. Will it eventually crap out, yes.

This test is not the be all, end all. It is simply what happened on those days of testing. For $20, I think there are better choices a person can make when buying a piston. In my experience, not all poly carb pistons are the same. There's always going to be a company charging twice as much for something that is only slightly better, or sometimes, slightly worse.
