Profiles as mentioned are really never a problem. The problem is in the nut area
for a chosen barrel. If you choose an M24 that comes in at 1.200, and a large
shank Savage needs to be 1.125, that can be a problem until you think outside
the box. Any barrel needs indexed and tenon cut true. So while it's indicated, it
does not take much extra machining to get what you want.....My M24 Bartlein
blank fitted my way......
