Maybe 3D baffles would work?
Quote from: miksatx on May 27, 2022, 10:36:53 AMMaybe 3D baffles would work?Sure could. Where is the broken part? Or do you want to replace all of the innards?If you provide constraining dimensions and need a STL print file, I can generate that for you. You will need to print it yourself or have it printed: https://www.gatewaytoairguns.org/GTA/index.php?topic=186969.0
I will print for him if he wants to fix this.

Mike,Please take a look at the design images below. If you approve, then please give Matt the go ahead to print the design. The STL print file is attached to this post. It is the top attachment, above the images.The central bore as designed is (a typical for .25 caliber) 8 mm or .315" in diameter; end to end. Except the "breech end" hole, at .90". I assume the rear endcap would just press against the stack, and that there is no reason to make the rear baffle stack hole smaller. This way, the air expansion volume ahead of the first baffle cone is controlled, with deliberate space for the air to go.The baffle stack diameter is a nominal 0.004" smaller in diameter than the casing ID. This is to allow for the print being slightly oversize, and clearance to go in. It may turn out that the OD needs to be reduced a bit more, although feedback from Matt about OD printed accuracy would be useful here.The length is 0.015" longer than the closed casing to enable some clamping force between the endcaps.To avoid "floating overhangs", the part should be printed with the muzzle end resting on the printer platen; although I am sure Matt can see that from the slanted features in the design.For your amusement, this fun exercise took 2 hours 20 minutes.
Thanks Mike. You will need to coordinate with Matt which version he is printing for you; shipping address and so on.Post to this thread once you have tried it out; whether it meets your expectations, or not. Or PM me.
Thanks Matt
