Don't know about the Max2 shafts but 5/16 is the most common size points for most carbon arrows. You need to measure your inserts that are in your arrows now to get a size. Just make sure the new points don't extend beyond the shaft or they'll be hard to remove from targets. Bigcountry is right about the inserts if they are the same as the aramid it will use the Type1 C E inserts. I believe the redhead # is 38-833-786-00.
