AA are glided out of the box, as are modern LGV and LGU.
I seen a few threads about gliding and buttoning pistons, they all relate to weihrauch, we’re any of the other guns like old bsa or we let’s ever glided?

Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
Gliding was popularised (pioneered?) by Venom and other 80s airgun tuning houses. At the time, most of their work was on HWs, hence the association between HWs and gliding.
You can button, glide or otherwise support both ends of most pistons, but it’s a lot easier to do well on actions with a central piston rod (HW, AA TX, etc) than those that engage the sear at the bottom.
What the hell is "piston gliding"?
If it just means making the piston fit for purpose, why not say so?.
Pistons where the sear engages the skirt need to be harder than the pistons with lathing rods, so they will often be harder to machine for synthetic buttons.
Glue on buttons can be used, but for example BSA supersport/lightning/superstar pistons leve very little room for glue on buttons as they are a quite close fit in the cylinder.
Too many airguns!
Friction is a wasteful by product of metal to metal contact. Instead of large expanses of piston, sliding against the inside walls of the rifle's chamber, actions run on nylatron etc bearings - in fact there's no metal to metal contact at all. Venom and Airmasters was doing this method back in the 80's. No marketing gimmick as owners of their fine rifles will tell you and the fact AA and Walther copied it for their production rifles.
