Tegra Arms AR-15 Stripped Lower Receiver, Carbon Fiber Composite Construction, Black

Tegra Arms AR-15 Stripped Lower Receiver, Carbon Fiber Composite, Black

The Tegra Arms AR-15 Stripped Lower Receiver is a carbon fiber composite Mil-Spec pattern AR-15 lower receiver in black. It ships completely stripped with no internal components included and is compatible with standard Mil-Spec AR-15 fire control groups, safety selectors, grips, Mil-Spec buffer tubes, and standard AR-15 upper receivers. Compatible with standard AR-15 and STANAG magazines across multiple calibers.

Key Features

• Stripped lower receiver, no internal components included
• Carbon fiber composite construction, black
• Compatible with Mil-Spec AR-15 fire control groups, safety selectors, grips, buffer tubes, and upper receivers
• Standard AR-15 and STANAG magazine compatible
• Multi-caliber compatible

Perfect For

• AR-15 builders sourcing a lightweight carbon fiber composite stripped lower receiver as the foundation of a custom build, supplying their own lower parts kit and buffer system
• Shooters looking to reduce overall build weight with a carbon fiber composite lower receiver in place of a standard aluminum receiver
• Builders who want a Mil-Spec compatible stripped lower in a non-traditional composite material without compromising compatibility with standard AR-15 components

Carbon Fiber Composite Construction

The Tegra Arms lower receiver is constructed from carbon fiber composite rather than the forged or billet aluminum used in conventional AR-15 lower receivers. Carbon fiber composite material combines carbon fiber strands with a polymer resin matrix, producing a finished component with a high strength-to-weight ratio. The primary practical advantage over aluminum is weight reduction. A carbon fiber composite lower receiver is lighter than its aluminum counterpart while maintaining the structural integrity needed to house and retain the fire control group and buffer system components under the stresses of normal use. The black finish is inherent to the carbon fiber composite material rather than applied as a surface coating.

Mil-Spec Compatibility

The receiver is compatible with the full range of standard Mil-Spec AR-15 components. Fire control groups, safety selectors, grips, Mil-Spec buffer tubes, and standard Mil-Spec AR-15 upper receivers all fit and function correctly with this lower. Standard AR-15 and STANAG pattern magazines are supported across the multi-caliber compatible mag well. All internal components must be sourced separately.
