Air Arms S4*0 barrel and cylinder swap

[Charlts]

Ryan, instead of changing the cylinder and barrel, just change the breech on both guns and then swap the barrels back... Will save the hassle of emptying the cylinders on both guns... Just watch for the O-ring between the action and breech (its quite small and thin...

He tried that earlier but tells me the 410 breech is different. I'll have a gander tomorrow, either way is pretty easy.

David you'll notice I said when empty! Thanks for the safety reminder.

Don't forget to empty the air out first!

And the air........ empty it, all of it....first.

"Obviously power will need to be altered when the barrel length changes,"

are you shure ?
the longer barrel for my tdr gave my an extra 1/2 fpe which brought it up to being "low"

the cyl on mine unscrewed easily (once empty) no trouble,
id taken off the end filler and reinserted it so as not to crush the open end,

as always heres a couple of pics ..
both cylinders with gun
and pre chamber
