Old Testament Firearms presents what will be the talk of the range! A crisp 5-Inch AR15 Pistol / SBR Upper Receiver Group chambered in 5.56 NATO (.223) that is a hoot to shoot and provides a clean, compact 5.56 upper. To ensure this 5" AR upper runs reliably it uses an adjustable gas block that allows you to tune gas system to your specific lower receiver to cycle consistently and without issues.
