This is the thread adaptor for the muzzle brake for the MARKSMAN and marksman prs suppressors.

Please select the correct muzzle thread from the drop down menu.

MOUNTING THE A-TEC PRS 3 MOD / MARKSMAN BRAKE

Do a dry run of the below steps before adding thread lock. Especially regarding the timing of the brake.

Place the rifle in a vice.
Thoroughly clean and degrease all components and threads.
Screw the stainless steel thread adaptor all the way into the suppressor/muzzlebrake and one full turn out again. The thread adaptor has the small unthreaded section inserted first. When running through this the second time, after applying thread locker, wipe off any excess thread locker here.
Screw on and torque up the black contra nut against the rear shoulder of the suppressor/muzzlebrake with the supplied wrench. For barrels with larger diameter than 23mm at the shoulder: Ensure the rear face of the steel thread adaptor is slightly proud of the black contra nut, one thread is enough. This is so the barrel thread shoulder meets the adaptor surface and not the contra nut.
Now screw the suppressor/muzzlebrake with the thread adaptor and contra nut on to the rifle muzzle thread.
Grasp the suppressor/muzzlebrake and apply torque to the suppressor/muzzlebrake by hand so that the thread adaptor is tight on the muzzle thread shoulder. We are using the suppressor/muzzlebrake locked on by the contra nut to get the thread adaptor torqued up on the muzzle thread shoulder.
Grasp the suppressor/muzzlebrake and loosen only the contra nut with the wrench without loosening the thread adaptor on the muzzle thread.
Adjust the suppressor/muzzlebrake rotation so the brake gas ports are directed horizontal. Try screwing on further first. If you hit the stop before achieving level, unscrew until level.
Reapply torque to the contra nut while grasping the suppressor/muzzlebrake to lock it in the level position.
Now disassemble, apply thread locker to the internal thread of the suppressor/muzzlebrake to secure the adaptor into the suppressor/muzzlebrake when it cures. Do the above steps again to permanently attach. Use Loctite 638 or equivalent.
Let the thread locker set before attempting detachment from the rifle.
