HUXWRX Fixed Barrel Spacer | 17-4 Stainless | MFG# 1836

The HUXWRX Fixed Barrel Spacer (MFG# 1836) is a purpose-built replacement spacer for fixed-barrel suppressor systems.

The spacer is described as a multi-fit part and is interchangeable with SilencerCo and Rugged fixed barrel spacers, intended for use with HUXWRX RAD 9 and RAD 45 suppressors.

Typical applications include routine suppressor-system maintenance and parts replacement for fixed-barrel pistols, and use by gunsmiths or armorers performing suppressor installations on compatible hosts.
