Good luck and please post what you find. My dedicated turkey hunting shotgun is a 12 gauge BPS; while it is a fine shotgun which functions flawlessly I have found the availability of after-market products to be skimpy. I would like to put an ATI stock (adjustable length and comb) on mine, but no mounting kit is available for the BPS.

One of the sanest, surest, and most generous joys of life comes from being happy over the good fortune of others.
