Barrel Threading,
Roan Mountain, TN

If you're adding a suppressor, compensator, or muzzle brake to a rifle or pistol, the barrel has to be cut with external threads that match your device exactly. At 2nd Amendment Arts in Roan Mountain, TN, we cut, crown, and verify every threaded barrel by hand on precision equipment, so the fit is square, concentric, and safe the first time.

What Barrel Threading Involves:

Barrel threading is the process of cutting external threads onto the muzzle end of a barrel so a suppressor, flash hider, compensator, or other muzzle device can be attached securely. The threads have to be cut on-center with the bore — even a small amount of runout can cause baffle strikes on a suppressor or inconsistent accuracy.

We work on rifle and pistol barrels in the common calibers and thread pitches, and can advise on the right pitch for your intended muzzle device if you're not sure.

Our Process:

We start by measuring your bore and confirming caliber, then indicate the barrel in the lathe so the cut is truly concentric with the bore rather than the outside diameter of the barrel. We cut threads to the correct pitch and length, then recrown the muzzle so the crown is square and undamaged. Every barrel is checked for runout before it leaves the shop.Why Choose 2nd Amendment Arts

Barrel work is precision machining, not a job for a hand die and a vise. We indicate every barrel in the lathe to confirm true concentricity with the bore, not just the exterior — the difference that keeps a suppressor from baffle-striking and keeps your accuracy consistent.

Frequently Asked Questions

Do I need a tax stamp before you thread my barrel?

Threading a barrel by itself does not require a tax stamp — that requirement applies to regulated items like suppressors, not to the threading service itself. If you're not sure how your specific build is classified, call us and we can talk through it.

What calibers and thread pitches do you work with?

We thread the common rifle and pistol calibers and can match thread pitch to whatever muzzle device you're installing. Call (423) 957-1149 with your caliber and device to confirm turnaround.

Do you thread stainless and chrome-lined barrels?

Yes, material and lining don't change the process, though certain coatings can affect tooling choice. Bring the barrel in or call ahead to discuss.

How long does barrel threading take?

Most threading jobs are quick, but turnaround depends on current shop volume. Call ahead for a current estimate.
