Description
The MasterPiece Arms 34mm 1.250" 0 MOA Scope Mount is a one-piece optic mount designed for serious bolt action shooters who need their point of impact to stay put. It's built to carry a 34mm main tube at a 1.25" centerline height, which handles larger objectives up to 56mm without the bell crowding your barrel. If you've spent any time around precision rifle crowds, you already know this mount by reputation, and the performance backs it up.
What Makes the MPA BA 34mm Mount Different
This mount runs a NATO-spec rail interface that pulls the body down onto the top of your Picatinny rail rather than pinching it from the sides. The result is over 3.5 inches of rail contact and a far more secure grip than a lot of competing designs. It's precision machined from 6061-T6 aluminum and finished in a hard-coat T3 Mil-Spec anodize, so it shrugs off field abuse and keeps looking sharp.
Absolute Return to Zero You Can Trust
Multiple locking lugs on the bottom of the rail interface give you a true absolute return to zero. That means you can pull the optic and remount it, or move the whole mount between rifles, and dial back to your known settings with confidence. The interface is cut to engage both in-spec and out-of-spec rails, so it plays nice even when your base isn't perfect.
Proven at the Highest Level
This isn't a mount that just looks good on paper. MPA's BA mounts have carried the optics of shooters winning PRS, NRL, and F-Class matches, and the brand has consistently ranked among the most-used scope mounts in Precision Rifle Series gear surveys. The horizontal split rings and 18-8 stainless hardware round out a package that's earned its spot on a lot of winning rifles. It carries a lifetime warranty.

Frequently Asked Questions
What size optic does the MasterPiece Arms 34mm 1.250" mount fit?
This mount is built for optics with a 34mm main tube. The 1.250" height gives you plenty of clearance for large objective lenses up to 56mm on a 34mm scope, so bigger glass clears the barrel without issue.
Does this MPA mount offer return to zero if I remove and remount my scope?
Yes. It features absolute return to zero through multiple locking lugs on the bottom of the rail interface. You can pull it off and reinstall it, or move it to another rifle, and get back to your zero with simple, predictable adjustments.
Will the MasterPiece Arms mount work on my Picatinny rail if it's slightly out of spec?
It should. The NATO-spec rail interface is designed to ensure positive engagement on both in-spec and out-of-spec rail systems. Instead of pinching the sides of the rail, it pulls down onto the top for over 3.5 inches of solid contact.
Is this a 0 MOA or 20 MOA mount?
This is the 0 MOA version, meaning it sits flat with no built-in forward cant. If you shoot extreme long range and want extra elevation built into the mount, MPA also offers a 20 MOA option, but this listing is the zero-cant model.
