Welcome aboard buddy, this is the place to go for info and parts for NRF/H&R's (now by Remington).
Yes, they sell wooden stocks for your gun and it is easy to swap them out. Are you planning on using a Red Dot or optic sight on youyr turkey gun? If so you might be better served by a Monte Carlo stock set up, if not, and you are planning on using iron sights be sure to get a straight staight (non-Monte Carlo) stock so you can use the sights.
As far as the longer forearms, I believe they are made for the heavy profile 10 gauge or heavy (thick walled) 12 gauge USH's (Ultra Slug Hunter) slug guns.
you have a PM incoming I may have a set of stocks for you, e-mail me if you can....<><....
