Sons Of Liberty Gun Works A5 Receiver Extension 9-Position Black

The Sons Of Liberty Gun Works A5 Receiver Extension is a buffer tube built to the A5 length configuration used on Mil-Spec AR-15 lower receivers. It is intended for shooters who want to tailor stock length of pull to body armor, clothing layers, or personal preference.

The tube offers a 9-position adjustment range and a black anodized finish that protects against wear from repeated stock adjustments and handling. It is designed for Mil-Spec AR-15 and AR-308 pattern lowers and uses standard Mil-Spec buffer tube hardware.

Because the A5 system runs on its own proprietary buffer and spring, sold separately, this extension is part of a complete A5 upgrade rather than a drop-in replacement for a standard carbine buffer tube. The matching buffer and spring must be installed to use it.
