Accommodating firearm bushing

Abstract

A barrel bushing and retained bias assembly are provided for engaging a barrel of a firearm to accommodate relative longitudinal movement of the barrel bushing and the barrel. The barrel bushing includes a retaining channel for retaining the bias assembly, such that a portion of the bias assembly extends into a bore of the barrel bushing to contact and be partly compressed by the outside diameter of the barrel.
