DNZ makes a 20 moa one piece mount in tactical model for sure but possibly game reaper also. If you look up model number on their website and then order it on Amazon you can return it if it doesn't work out. I know lots of people really drown the 9.5 twist rate but there are upsides to it if you shoot around 160 grain bullets or lighter. They shoot flatter to 500 yards for hunting and stills retain the same energy. The wear on barrel is reduced. The rotational pull right is less at longer shots. To summarize, unless you are married to shooting bullets above the 160s (which there is a ton of options for) then the 9.5 twist is not limiting at all. The advantage of 175 and higher is at 700 yard target shooting or beyond and what I consider unethical hunting distances for myself which is beyond 500 yards. Good luck to ya
