Looking to add a bipod to my black synthetic stocked Browning. 300 WIN MAG BAR Safari.w/BOSS . I DO want to have the option of adding a sling to it later too. This is primarily used for long range ground field use so a 9-13 adjustable would be fine. Thank you in advance for your advice. Quality and durabilty ARE as important as price, oh and one more thing, its gotta be made in the USA.
