This black bottomline ASA is drilled and tapped with 3 pressure exit holes. Now you can determine the hose configuration most comfortable for your shooting position; left, right or center line output. After choosing, you can then simply plug the other two holes or screw in a gauge if you prefer. The Shocktech 3 hole BL ASA is constructed of lightweight quality aluminum with a thick coat of anodizing. All Shocktech products are made right here in the good ol USA.
