Truglo AC22040 Cantilever Scope Mount 30mm Ring System

The Truglo AC22040 Cantilever Mount delivers precision optics positioning for shooters demanding reliable performance from their 30mm scope systems. This single-piece cantilever design eliminates alignment issues common with two-piece ring setups while providing extended eye relief positioning.

What Makes This Different

Unlike traditional two-piece ring mounts that can introduce mechanical stress and alignment problems, this cantilever system maintains perfect scope alignment through a rigid one-piece construction. The extended forward positioning accommodates modern variable power optics requiring specific eye relief distances. Machined from aircraft-grade aluminum, it maintains zero under recoil forces that cause lesser mounts to shift.

Key Features

• Single-piece cantilever design eliminates ring alignment issues
• 30mm ring diameter fits standard variable power scopes
• Extended forward positioning for proper eye relief setup
• Aircraft-grade aluminum construction resists impact and corrosion
• Picatinny rail compatible with MIL-STD-1913 specifications
• Precision-machined surfaces ensure consistent clamping pressure
• Low-profile design minimizes snag points and overall height

Field testing demonstrates this mount maintains zero through hundreds of rounds across multiple calibers from .223 Remington to .308 Winchester. The cantilever design proves particularly effective for AR-platform rifles where scope positioning affects cheek weld consistency. Weather exposure testing shows the hard-anodized finish resists corrosion in marine environments and temperature extremes from -20°F to 140°F.
