One-Piece Scope Bases Are the Best Choice
A one-piece scope base offers superior performance compared to traditional two-piece bases. By creating one continuous mounting platform, it improves alignment, increases stability, and gives you more flexibility when positioning your optic.
Greater stability with fewer potential failure points
Improved durability under recoil
Better scope alignment and accuracy retention
More flexibility for proper eye relief adjustment
Ideal for hunting, plinking, and general use
Picatinny vs Weaver – Why Picatinny Is the Superior Choice
While Weaver-style bases were once common, Picatinny rails have become the modern standard due to their superior strength, consistency, and compatibility.
Standardized slot spacing ensures repeatable optic placement
Compatible with both Picatinny and Weaver-style rings
Stronger and more durable under recoil
Greater flexibility for optic placement
Modern optics mounting standard
0 MOA – Ideal for Traditional Hunting and Target Shooting
This rail features 0 MOA of built-in elevation, making it the best choice for traditional hunting, plinking, and target shooting ranges where additional scope cant is not needed.
0 MOA: Ideal for most hunting and shooting from 25–200 yards
20 MOA: Recommended when additional elevation adjustment is needed for longer-distance shooting
Built for Durability
Every HD rail is machined from solid 7075 T6 aluminum, then tumbled, sandblasted, and finished with matte black hardcoat anodizing. The result is a durable, corrosion-resistant finish that blends cleanly with your rifle and stands up to field use.
Installation Notes
For proper installation, torque the mounting screws to 20 inch-pounds using the included T-10 Torx bit. We recommend applying one drop of blue Loctite to each mounting screw. Loctite is sold separately.
