The biggest difference between the two baffles is that the red one makes contact with the bar and the grey one does not.
If you are using a very fine powder like Win. AA Lite you will have powder coming out between the baffle and bar on the grey one. Then you have to use the brass washer.



The one thing I do not like about the red baffle is that the threads for the bottle end are not quite right and you have to play with it to make it fit right.
