And spring room .
Airmasters were fitting these in the 1980’s, I have a few of their tuned HW77’s rifles with them fitted

How would a ptfe washer sandwiched between two steel washers fare?
The more I think I know, the more I realise the less I know.
I've just bought a txsr with one of these bearings fitted between the rear guide and the trigger block. It does shoot very well. Would it be advisable to remove it?
It won't wear the trigger block , if it's a flat race ie three piece , they are designed so one piece stays still, it's the whole point of a thrust race.
PTFE deforms and migrated , so you will probably see velocity varying , delrin is probably better.
Your piston rotates in the tx anyhow, just make sure your piston weight/ top hat isn't stuck and grease it .
I have noticed, admittedly in my budget guns that the rotation has been pushed back (layman's terms) to the rear of the spring guide vs the end block.
I saw this most visibly in my Paratrooper even though it's spring guide allows rotation there is a shiney circle worn into the rear block corresponding to a similar circle of the rear of the spring guide.
It just goes to show how important a good spring bearing set up is.
