American Rifle Company 40mm Medium Scope Rings, Black

The American Rifle Company 40mm Medium Scope Rings, Black (American Rifle Company part no. MB-R-40-28) are two-piece steel scope rings from American Rifle Company, bored for a 40mm main tube and built to a medium height that gives a balanced middle-ground height that clears most common objective bells and iron sight setups. Clamping to a standard Picatinny rail, they’re built to hold a scope rock-solid under recoil for precision rifle competitors and long-range hunters who can’t afford a ring shifting zero mid-string.

Key Specifications

• Bored for a 40mm main-tube scope.
• Built to medium height (1.10”), measured from the rail interface to the ring’s tube centerline.
• Clamps to a standard Picatinny rail for broad mounting compatibility.
• Finished in black to match most factory rifle finishes.
• Engineered for a rigid, no-slip clamp on the scope tube under recoil.

Frequently Asked Questions

Will these fit a different tube diameter? No, these rings are bored specifically for a 40mm main tube and will not securely clamp a different diameter.

Why choose medium height? Ring height controls scope-to-bore clearance and cheek weld; medium height gives a balanced middle-ground height that clears most common objective bells and iron sight setups.
