High-Performance Picatinny Rail Optics Mount
The Talley Manufacturing Picatinny Rail provides a rock-solid, precise mounting platform specifically designed to match the receiver profile of Christensen Arms bolt-action rifles.

It features a durable, Type III hard-coat anodized black finish to withstand harsh field environments and eliminate corrosion risk.
High-Performance Picatinny Rail Optics Mount
This high-precision mounting system is engineered to integrate perfectly with the top receiver geometry of popular firearm models. It fits seamlessly on the Christensen Arms Mesa, Ridgeline, and Mesa TLR series. Because these firearms utilize a receiver footprint modeled after the iconic Remington 700 action, the base aligns perfectly with factory-tapped screw holes. This guarantees a straightforward installation process without requiring additional custom gunsmithing or modification

Choosing 0 MOA vs. 20 MOA
Selecting the proper built-in MOA depends heavily on your specific shooting application and target distances:
- 0 MOA Flat Rail: Best for hunters and target shooters operating within traditional distances (0 to 500 yards). It allows you to keep your scope reticle closer to the center of its internal elevation adjustment range for close-to-medium range zeros.
- 20 MOA Canted Rail: Crucial for long-range precision marksmen aiming past 500 yards. This built-in downward slope provides an extra 20 Minutes of Angle (MOA) of upward elevation adjustment within your scope turret, ensuring you do not run out of adjustment clicks when dialing for extreme distances.
Loctitie?
- Although not always necessary, using Loctite for the screws going in the receiver is perfectly fine. We do not recommend using anything stronger than Loctite Blue 242. We do not recommend using Loctite on the ring screws. Always test fit before applying any Loctite.
