8" Arm Bar with Stabilizer

The JMac Customs® 8" 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.
