I am relatively new to long distance shooting. I have a Accuracy International AT with a Nightforce ATACR 5x25 optic mounted on the AI 20 MOA rail. My scope mount is a Masterpiece Arms BA mount. I lost the receipt for the MPA mount, but I think the height is 1.25" from the rail. The issue is I have a very large head and I am having a hard time getting proper check weld. In fact, I am having to really lower my head about an inch lower then is comfortable. The AI adjustable stock is set at its lowest setting. So I cannot adjust the stock to make it lower. What are my options other then getting a new scope mount? I really like my MPA mount. Are there rail adaptors I could use? If so, any cons to getting one of those? I assume its just one more thing to make sure is mounted correctly etc. I think I need at least another half inch of height on the mount. If anyone out there can assist me that would be awesome. I only shoot out to 600 yards at this point due to range constrictions. Please help advise me if you have the time. Thank you in advance. AB
