Hello: I have just purchased a slightly used SA08. It came with all its original packaging and manuals. I noticed that the 3 chokes do not state if they are full, modified or improved cylinder. The manual does not describe which is which either. They each have either one nick, 3 nicks, or 4 nicks across the top near the wrench marks. Can any of you assist with this question? The manual does not provide any instructions for the use of the stock shims either. When I purchased my Mossberg 935, 5 years ago, each shim was identified by thickness and number and it came with detailed installation instructions. I assume the installation of the shims will be similar but if anyone can provide some help it would be appreciated.
Thanks, Rick in London.
