Hey @Apohlo, your cousin here. Welcome to the forum. If you want to learn a bit of the heritage of your gun, look up Claudio Flores, the 2018 Extreme Bench Rest champ.
Saber tactical makes a picatinny extension, or you might be able to find something sturdy by UTG. There is also the Saber Tactical bottle clamps if you want to get the bipod as far forward as you can. Or maybe @L.Leon is right that it will work on the rail as is. He is a bit of a Brocock guru here.
Blew the breech seal (again). De-gassed and decided to inspect the regulator and verify operation as I have been hearing a bit of a gurgle post-shot. Turns out a couple of the huma reg o-rings have seen better days, as well as the fill port bonded washer. Seemed to have been excessive oil outside. Rings and parts are on order and I started a thread to showcase the rebuild here on AGN! https://www.airgunnation.com/thread...bantam-sniper-hr-magnum.1268926/#post-1278884
