EGW HD Henry Octagon Barrel Picatinny Rail Scope Mount – 0 MOA

Upgrade your Henry octagon barrel rifle with a strong, precision-machined optics mounting solution. This EGW HD one-piece Picatinny rail provides a rigid foundation for mounting a scope while maintaining repeatability, durability, and clean fitment.

Machined from solid 7075 T6 aircraft-grade aluminum, this rail is built for shooters who want strength without unnecessary weight. The full-length Picatinny cross slots allow flexible scope ring placement, making it easier to set proper eye relief.

This mount is specifically contoured for Henry octagon barrels. It will not seat properly or safely on round barrel models.

Compatible Rifles

• Henry Golden Boy .22 LR with octagon barrel (Model H004)
• Henry 1st Generation Big Boy with octagon barrel (Model H006)

Critical Fitment Warning

This rail is designed for Henry rifles with octagon barrels only. It is contoured to sit flush against the flat top surface of the octagon barrel. This rail will not properly fit Henry rifles with round barrels.

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.
