for those who get the knurled can or modular linear comps for the shroud- this goes at the end of your baffle stack. this is made to fit the baffles of the Knurled comp but it could very easily be stretched to fit the other ones

so it goes, baffles, wipe end cap, wipe, screw on front end cap. you want the wipe to take up the whole surface or nearly that of this cap so you can pinch the wipe between this piece and the front screw cap
