Are they the same as p15 baffles? I know the xm1 is a p15 clone and the outer shroud appears the same. If so, I may have some on a box of bit, somewhere. If I find them,you can have the FOC. But my honest advice would be save up and get a cf shroud from Mark Dempsey. Makes them whisper quiet - had one on both of my p15 rifles in 177 and 22. The factory baffles are loose in the shroud, from experience
Post a pic of the baffles, mate.
