9" Arm Bar with Stabilizer

The JMac Customs™ 9" Arm Bar offers unparalleled adaptability, allowing for seamless conversion between a brace or stock. This configuration includes our Arm Bar Stabalizer, which attaches directly to the rear of the Arm Bar. This arm bar can also be used in a stock setup when paired with a Folding Buttplate (sold separately).

Lightweight yet exceptionally rigid, the Arm Bar excels in both form and function.

The ARM BAR™ Stabilizer is JMAC’s purpose-built solution for enhanced one-handed control and support — engineered to integrate directly with the rear of our ARM BAR™ platform.

Designed to replace the previous AB-BA adapter setup, this stabilizer bolts directly to the rear of the ARM BAR™, creating a streamlined, rigid interface without the need for third-party components.

Built for shooters who demand control and durability, the ARM BAR™ Stabilizer allows the firearm to be extended and stabilized against the forearm for improved handling and support.

Key Features:

• Modular Design: Convert between brace and stock with multiple mounting configurations
• Raised Design allows for better arm fitment under the brace
• Drilled and tapped for cheek risers
• SIG Folding Mechanism Compatibility for smooth, reliable folding.
• 1 threaded hole for mounting bolts (included)
• Can be adjusted up and down for height

Specifications:

• 7075 T6 Aluminum for superior strength-to-weight ratio
• Type 3 Hard-Coat Anodized finish for enhanced durability and corrosion resistance

Attaching a stock to a pistol creates an SBR, requiring NFA approval. Follow all local/state/federal laws.
