Masterpiece Arms MPA BA Bolt Action Mount - 34mm 1.125" 0 MOA One-Piece MPA Bamount-34-1125

The Masterpiece Arms MPA BA Bolt Action Mount is a precision one-piece scope mount engineered for shooters running high-performance optics on bolt-action rifles. If you're building a dedicated long-range platform or upgrading a hunting rifle with a quality scope, this 34mm mount delivers the rigid, zero-shift performance that matters downrange. It's the kind of mount that gets out of the way and lets your optic do its job—no wiggle, no excuses.

Built from 6061 T6 aluminum and finished in hard-coat Mil-Spec anodize, the MPA BA mount is designed to handle the recoil impulse and hold your zero shot after shot. The one-piece design eliminates the compliance issues that can creep into two-ring systems, and the horizontal split rings let you dial in scope height without fuss. What really sets this mount apart is the rail interface: it's engineered with multiple locking lugs on the bottom that engage your rifle's Picatinny base, ensuring solid lockup whether your base is dead-on spec or slightly out. That translates to confidence in the field—you mount it, verify your zero, and move on.

The 0 MOA configuration and 1.125" height put your 34mm tube in a natural, comfortable cheek weld position on most modern bolt guns. The interface provides over 3.5" of contact rail, which means extreme stability and absolute return to zero if you need to remove and reinstall your scope. Whether you're zeroing at the range or dialing in a new hunting rifle, this is a mount built to keep your optic exactly where you put it.

Frequently Asked Questions

What rifles does the MPA BA mount fit?

The MPA BA mount is designed for bolt-action rifles equipped with Picatinny rail scope bases. It works with both in-spec and out-of-spec rail systems, so as long as your rifle has a Picatinny-compatible base, this mount will secure a solid lockup.

Can I remove and remount my scope without losing zero?

Yes. The multiple locking lugs and over 3.5" of rail interface provide absolute return to zero. If you need to take the scope off and reinstall it, the mount's design ensures it returns to the same position.

What does "0 MOA" mean?

0 MOA means this mount has no built-in elevation angle. It mounts flat and level to your rifle's rail, putting all elevation adjustment on your scope's turrets. This is the standard choice for most hunters and precision shooters.

Is this mount compatible with 30mm scopes?

No. This is a 34mm mount and is designed to hold 34mm scope tubes. A 30mm scope would not fit properly in the split rings.
