ADL Model. Struggling here but I’m sure I’m an idiot and missing something. The HS Precision stock has a void, open space where the front trigger guard screw would go. This void goes all the way up behind the mag box. So there is nothing to screw the screw to. Is this a stock that requires a single hole trigger guard? If so does the front slide in and overlap or something. Any links to help or buy whatever this stock takes would be great. Thanks.
