Air Arms Pro Sport Caliber Change?

[maxtrouble]

How hard is it to change calibers on the Pro Sport? Has anyone done this? Is it as easy as changing a spring? Pyramid does not have the item listed. I can only find them available at Chambers. Item - BRL074.

If the barrel is attached the same way it is as on an HW97 it would be a difficult process. At least for me any way.
A lot harder than changing a spring.

so, from the parts diagram you would have to take all the guts out, get a long extension the right socket and take off the nut and the barrel will come out
how i would use an Air wrench and maybe the barrel is loose or needs a few gentle taps

I can change from 177 to .22 in about half hour. Steve!

@Ozwald - Glad to hear it is possible. I looked for a video and all I can find are spring changes or spring tuning. Is there a video somewhere on the process? Do you have any words of wisdom on how to do it?

It is not hard to do, the shroud is the hardest part trying to remove it from the barrel use lots of heat. the nut comes of pretty easy the right socket and an extension and a padded vice will do it. good luck. Steve!

Is it a left hand nut thread or standard right hand thread

Didn't seem like anyone had posted this video so if you haven't seen it... This is a TX200 but the process should be similar.

Might check out this thread which mentions a few other threads too. https://www.gatewaytoairguns.org/GTA/index.php?topic=50181.0
