*Please note, items must be unloaded, ensure there is no round in the chamber and that the magazine or tube is empty before shipping or dropping off with us.
*Silencer Central can not accept firearms that do not have a visible serial number unless documentation is included. If we receive a firearm with no visible serial number & lacking documentation, the item will be turned over to the ATF.
* Silencer Central Uses 4″x8″x48″ boxes, please ensure your riffle/barrel will fit into the container for return shipping. Silencer Central will not accept odd-shaped cases such as guitar cases or oversized gun cases.

We will send you a pre-packaged box (4″ x 8″ x 48″) containing two soft cases with a prepaid return shipping label. You will remove all accessories from your rifle and package your barrel(s) in the provided soft cases, fill out the order form and secure it in the soft case, then use the prepaid label to send it off to Silencer Central.

Of Course! Stop by our Sioux Falls location at 4901 N 4th Ave, Sioux Falls, SD 57104 and drop off your barrels for threading. Be sure to have all accessories removed before dropping them off. Please note, we do not offer a same-day threading service our standard 7 – 10 day turnaround time still applies.

Items dropped off at our Sioux Falls, SD location may be picked up in the store or shipped to you for $19.99.

If your barrel was shipped with a 360 Mailing Program, orders will be shipped to you when the work is completed.

Rifles: Please remove all accessories such as scopes and rings, bi-pods, slings, lights, etc… Bolt action rifles should be left in the stock whenever possible. If you must ship the barreled action by itself, we strongly advise the removal of the trigger assembly. This avoids the chance of having the fragile trigger group break or suffer damage in shipping.

AR-15 or AR-10 Type Uppers: In most cases, you do not need to remove the barrel. Just ship the entire upper, minus the bolt carrier group, and all rail-mounted accessories/sights.

*Silencer Central Cannot accept Short-Barreled Rifles ( SBR- barrel length less than 16″), unless a copy of your Form 4 can be included with the shipment.

For the requested thread pitch, accurately verify suppressor thread pitch. Choosing to leave the thread pitch option blank, will result in the barrel being threaded based on caliber. If this is not possible due to barrel dimensions, then a follow up email will be sent and clarified before any work is done.

No, not all suppressors are threaded the same. There are a variety of different thread pitches, which is why you may need an adapter. There are a few popular military silencers whose thread pitches are as close to “standard” as we get. Still, you’ll probably want a few adapters on hand.

For more information on silencers and barrel threading, visit our full suppressor thread size guide.

We thread to the recommendation and guidelines of the company that builds our suppressors. We always thread to caliber first and then cross reference with diameter of the barrel. Most of our customers have the gunsmith determine the best thread pitch for each barrel to ensure the best results.

If you absolutely want a specific thread, you can put it in the note section on the threading order form and the gunsmith will try to fulfill your request, if diameter allows. We offer a thread adapter that steps up a 1/2 x 28 thread to 5/8 x 24 if your thread is smaller than your silencers thread pitch.

Yes, you can put a suppressor on a non-threaded barrel, although it can be a little tricky. Most suppressors are made for a threaded barrel, so you’ll need to find a different way to attach it.

There are threading adapters on the market, but the best way to attach a silencer to a non-threaded barrel is to get your barrel threaded. Here at Silencer Central, we have our own threading service, where you can send us your barrel and get it threaded starting at $99.99.

Yes, you can. We recommend threading your barrel to attach your suppressor. Threading an unthreaded barrel is super easy with our Threading Central HAAS single point threading machine. You can send us your barrel safely, from anywhere in the country, and we will return it expertly threaded.

At this time we are only able to thread a blowback-style pistol like a Ruger Mark series pistol. We can look to see if an aftermarket barrel exists for your pistol and (if available) order one for you. Payment is required when ordering and our team will ship you the barrel once the barrel is received at our HQ.

We do not make custom barrels. We are set up to mainly do threading and at this time are not setup to build or install barrels.
