The BANISH 30 HUB Retrofit Kit allows you to convert your BANISH 30 suppressor from a direct thread mount to the industry standard 1.375x24 HUB mounting system. This kit includes an Industry Hub Adapter and a custom installation tool. Converting your BANISH 30 to a hub mount gives you additional flexibility in how you mount your suppressor, adding additional versatility to one of the industry's most versatile silencers. Note: If your BANISH 30's serial number starts with B0 or B30, you will need the Spacer Compatible version. All other BANISH 30s require the standard version.
