I have RRS BAI-AT rail as shown on my AT and would like to add the HRD Gear 9" to get rid of the Big Dog spigot mount to save some weight and to be able to move/slide the bipod faster and more easily . The HRD rail will extend around 5" beyond the chassis. Does anyone have this setup or know anyone that is running this setup? Any issues with the 9" HRD rail installation when BAI-AT is already installed or that the HRD rail is extending the forend/chassis by 5" or 6"?
