Masterpiece Arms BA Rings are expertly engineered for the discerning hunter who demands the best to ensure optic consistency and maintain perfect alignment for that critical shot. Sold as a set, these rings feature a built-in leveling system on one cap, designed with a specific profile and location that allows the shooter to easily see the level with their weak eye while keeping the strong eye focused on the target through the ocular lens. This innovative design enables the shooter to remain on target without needing to take their eyes off the prize, ensuring the rifle stays perfectly aligned. The low-profile, snag-free placement of the leveling system prevents it from catching on branches or heavy brush during field use, making it ideal for rugged terrain. With a width of 1 inches, the rings provide an extensive clamping surface area, offering superior stability compared to similar products. The BA Rings are designed with a grip on the optic tube that effectively eliminates any chance of movement. Don't allow flimsy, lightweight rings to hinder your efforts in harvesting that trophy you've worked so hard for. Like all Masterpiece Arms products, the MPA BA Rings are purpose-built to deliver the highest level of assurance for the hunter, their rifle and their optic, ensuring every shot counts.
