Abstract

A quick-attach/quick-detach coupler assembly used for mounting a hand guard around a rifle barrel, allowing prompt barrel change. The coupler assembly has a generally cylindrical barrel nut with a plurality of external rail-mounting teeth centrally around its exterior circumference, interior threads for connection to the upper receiver of a rifle, and multiple fastener holes allowing set screws to contact a two-piece separable extension and provide anti-rotational engagement between it and the barrel nut. The barrel nut's interior threads also connect it to the extension. A tool configured as a hand guard fastener and stored/carried on the hand guard is easily accessed to tighten/release the set screws. The tool's handle may also be configured to engage notches on the extension's barrel end and facilitate its release from the barrel nut. The coupler assembly will mount almost every hand guard currently marketed to the upper receiver of the AR family of rifles.
