WOW, I did not expect such a detailed response in short notice, thanks!

There are a few things I still don't understand.

Can you explain a little more on how the hammer bearing is used to lock down the sear? I have not taken apart my hammer assembly yet so I have not seen the full sear / mechanism but I dont understand how it could help with locking down the hammer. From my perspective, all I see is the little notch in the hammer getting stuck on the sear. How does the little bearing on the opposite side help lock it down?

When you say that the hammer bearing provides a cushion to the hammer, do you mean when the trigger is pulled and the hammer is released and strikes the back of the bbu?

Is the small piece of plastic that screws into the nozzle just there to make sure that the floating valve does not go back to far and to direct air flow to the back?

I noticed that on the piston in the bbu, there is a small piece of rubber attached to the bottom. What function does this piece serve?

One more thing, I dont really understand how the blowback works. Does the gas that is propelled towards the back of the bbu stay in the air nozzle, and how does it propel the slide back?

My gun worked fine before, even in the winter, so it has to be something.
Oh yeah, I forgot to mention that my mags are warm to start out with, but after shooting them, they feel FREEZING, super cold, complete difference.

Also yesterday when I was tinkering with the bbu, I noticed that even with the screw fully tightened for the piston head, it still wobbled a bit. I put a tiny o ring under the piston head, but the problem was still happening.

Thanks for all of the help.
