I remember reading years ago that the baffles are loose in the shroud and supposedly sit low in the shroud, so they are probably not too close to the muzzle. I don't know about replacement/drop-in baffles in the aftermarket (I don't own AA guns), but I am sure someone could make new baffles for the TX200 if they wanted to.
I know nothing of the baffles but recall a Steve on GTA had fits tuning his Pro Sport. The pellets were clipping a misaligned baffle. His handle was Nitrocrushr. I found an article by him but the pictures are not coming up on my computer. https://www.gatewaytoairguns.org/GTA/index.php?topic=95053.0
