Terry desgined this unit to be stronger and more reliable than any other out their. He deals with people that their precision rifles have lives that count on them and after hearing stories of snipers crawling tinto position and finding that their cheek piece was missing or way out of adjustment he desgined this one. When you build a tactical rifle generaly you use a better bottom metal like from badger or the like and those use 3/16 socket head screws for the action , so with this in mind he desgined heis comb piece to be adjustable with only a 3/16 allen to keep from having several wrenches.
These are the same adjustment pieces that Manners stocks are using in their tactical stocks.
Terry doesen't have a web page that I know of but if you call him and leave a message he will call you back quickley ,hes a very cool guy to do buisness with and apparently one hell of a rifle builder. His place is a couple hrs NW of me and have been thinking about running up their to meet with him and possible shoot in a couple matches that he goes to.
