HUB/Plan B Drive Adapters
Tools Needed:
1 ¼” Crowsfoot Wrench
½” Drive Torque Wrench
We recommend Flexbar Rocksett high temperature adhesive to attach any HUB type suppressor adapter to the suppressor to prevent the adapter from turning independently of the suppressor during installation/removal.
We also recommend Method Dynamics suppressor grease on any muzzle device to HUB adapter interface to prevent galling/carbon lock. An anti-seize grease must be used or your warranty will be voided.
Remove existing HUB type adapter.
Apply Rocksett Adhesive to external threads on the HUB adapter only.
Thread into suppressor and torque to 25 ft. lbs. or 34 Nm with a 1 ¼” wrench. You will need to apply a wrench to both the adapter and the suppressor to tighten correctly.
Allow the Rocksett to harden before use.
Attention: Always check alignment of the barrel, muzzle device, adapter, and suppressor with an alignment rod. Do not use it if the alignment rod is close to or touching the strike baffle or end cap of the suppressor. Failure to do this will void your warranty. Instructions for this at bottom of the page.
Direct Drive Adapters
Tools Needed:
13/16” Crowsfoot Wrench
½” Drive Torque Wrench
We recommend Flexbar Rocksett high temperature adhesive to attach any direct suppressor adapter to the suppressor to prevent the adapter from turning independently of the suppressor during installation/removal.
We also recommend Method Dynamics suppressor grease on any muzzle thread to direct adapter interface to prevent galling/carbon lock.
Remove existing HUB type adapter.
Apply Rocksett Adhesive to external threads on the direct adapter only.
Thread into suppressor and torque to 25 ft. lbs. or 34 Nm with a 13/16” wrench. You will need to apply a wrench to both the adapter and the suppressor to tighten correctly.
Allow the Rocksett to harden before use.

Do not use it if the alignment rod is close to or touching the strike baffle or end cap of the suppressor. Failure to do this will void your warranty. Instructions for this at bottom of the page.

Begin by making sure firearm is unloaded.
We recommend Flexbar Rocksett high temperature adhesive to attach any muzzle device to a barrel that will be used with a corresponding HUB type suppressor adapter to prevent the muzzle device from turning with the adapter/suppressor.
We also recommend Method Dynamics suppressor grease on any muzzle device to HUB adapter interface to prevent galling/carbon lock. An anti-seize grease must be used or your warranty will be voided.
If the muzzle device you are using needs to be timed for the ports to line up like on a muzzle brake, you will need to use a combination of the included shims to achieve the timing. This will take some trial and error before arriving at a solution.
Once this is achieved or if you did not need shims, apply Rocksett adhesive to the threads on the barrel only, install muzzle device and tighten to 33 ft. lbs. or 45 Nm using a 13/16” wrench.
Allow Rocksett to harden before use.
With an appropriate Suppressor Alignment Check Rod, an end user or gunsmith can verify alignment of the suppressor and mount device. Use of this tool is simple and should prevent baffle strikes.
To use the Suppressor Check Alignment Rod:
1. Properly mount your silencer to the firearm.
2. Insert Suppressor Alignment Check Rod down bore of the silencer and into the firearm bore until the end of the rod is flush with the endcap of your silencer.
3. Observe alignment and confirm rod is positioned near the center of the silencer bore, refer to the alignment images provided. Firearm may need to be rotated around bore to confirm alignment due to tolerance between the bore and check rod.
4. If mount and silencer are in alignment, remove rod and enjoy your suppressed firearm! • Barrel Threading Issues Not all barrel threading is created equal. Mass-produced firearms can sometimes have threads that aren’t perfectly concentric with the bore.
Even small deviations can lead to significant misalignment once the suppressor is attached.
• Muzzle Device Complications If you’re using a suppressor with a quick-detach system that attaches to a muzzle brake or flash hider, multiple points of potential misalignment are introduced. Each connection point can contribute to the overall alignment problem.
• Shoulder Inconsistencies The shoulder (where the barrel meets the threaded portion) should be square and consistent. Irregularities here can cause the suppressor to sit at a slight angle.
• Suppressor Manufacturing Variations While quality suppressors undergo rigorous quality control, manufacturing variations can still occur.
Even premium suppressors can have slight variances that, when combined with barrel threading issues, result in misalignment.
