Muzzle Threading & Moderator Fitting Service: Our muzzle threading and moderator fitting & testing service goes hand in hand with moderator manufacture.

The muzzle thread is the interface that joins the sound moderator to the rifle barrel. To prevent collision of projectiles against baffles and the resulting loss of accuracy it is absolutely imperative the muzzle is threaded exactly concentric to the center-line of the bore. A muzzle should never be threaded taking reference only from the outside of the barrel. The bore of the barrel is the governing factor, with many factory rifle barrels being slightly off center. Threading to tight tolerances can only be achieved by screw cutting on a machine designed to do the job correctly, and NEVER by hand tools.

We have years of experience in screw-cutting and are highly skilled in this procedure having threaded many thousands of barrels. We can machine your barrel with a perfectly concentric thread, ensuring you do not encounter problems with your sound moderator or any other muzzle attachment.

Paragraph 21.2 of the Federal Firearms Regulations states that machining a pressure bearing part of a firearm constitutes an act of firearms manufacture and in order to do this the person carrying out the work must have the necessary manufacturer’s permits detailed by paragraph 21 and 26 of the same law. The machining of a muzzle thread is definitely NOT a job for someone who works in a mechanics shop or something you should attempt at home. Threading a rifle barrel belongs firmly in the hands of a qualified and capable Riflesmith. Once a rifle barrel has been threaded it is required, by law, for the rifle to be re-presented for proof at one of the state run proof houses. We can take care of all this for you as part of our service.

We will choose the best method of machining the thread onto your barrel depending on firearm type. Machining will either be done on a Weiler lathe or a 5 axis CNC machining station.

With a muzzle thread cut exactly in line with the bore by Roedale Precision, you have peace of mind that you can fit any kind of muzzle brake or sound moderator with the correct thread type to your rifle. Each thread that we machine comes with a thread protection cap as part of the service.
