Why button?

[shrendi]

This is another of my basic questions that will probably seem obvious to everyone else, here goes anyway. Why button? When ever i strip my HW77 there is no disturbance to the moly coating on the piston, this seems to imply no contact. Is this unusual and most guns do have metal to metal contact and so benefit from buttons? I am probably missing something. Thanks

Please or i will start to feel leprosic.

On a top rifle there is less reason to button a piston, but it is done to reduce/eliminate the metal/metal contact and make cocking the rifle feel smoother.

That’s all buttoning dose make things feel smother, nothing more. I’ve buttoned a 335 and a B4 and I could feel the difference, the 335 benefited most the B4 improved but needs resurrection more than tuning.

Thanks, thats what i thought but you never know there could have been some mystical black art at work. Best to have a good piston fit in the first place and spend money on other areas.

Gonna stick my neck out here, I think buttoning a HW77/97 is totally unnecessary they will cock and shoot just as smoothly with careful polish and even more important decent lube

And so will the 80, no need for buttons just polish rearmost inch of piston, finish polish in same direction as travel for supersmooth cocking

Whats even more important is proper fitting springs and guides, and I like metallic rear guides still, unlike Venom who seem to use HW synthetic std rear guides these days, at the price they charge I would expect one of their made to measure metal guides, they did when Ivan was there

Thanks, again you have confirmed my long held belief, and yes i would expect a made to measure guide or what are you paying for?

agree here,,,,no need to button but use delrin spring guide and top hat etc,,,,,i make mine a nice sliding fit and polish the spring ends and use sparingly the grease

100% correct.
Its down to basic engineering, and HW seem to have it at 90%. With a tad more attention to QC they would be at 100%.
