Preparing for Your First Suppressor or SBR Purchase
Buying your first suppressor, silencer, or short-barreled rifle can feel complicated, but the process is much easier when your accounts, paperwork, fingerprints, and dealer assignment are set up correctly from the beginning.
Stonebridge Gunworks helps Missouri customers select the right NFA item, order through our available channels, complete the Silencer Shop and ATF eForms steps, certify the Form 4, and complete final pickup after approval.
Stonebridge or Silencer Shop Orders
NFA items purchased directly through Stonebridge Gunworks, or ordered through our Silencer Shop dealer link and transferred to us, qualify for our normal partner process. No additional Stonebridge Form 4 processing fee applies to these orders.
Outside NFA Transfers
Purchasing an NFA item from an outside source and transferring it to us:
Customers in the same reduced-eligible categories as our FFL transfers — active-duty law enforcement, military, and federal agents; active USPSA members; the Abundant Life Security Team; and approved industry partners — receive a reduced fee of $60.
How & When We Assign Your Item
- •In-stock suppressors: items in our inventory can be assigned to your account the same day for processing.
- •Silencer Shop orders: once your suppressor is received from Silencer Shop, we'll reach out by text when your Form 4 is ready to certify — certification can be completed remotely.
- •Outside transfers: once your item is received, we assign it to your Silencer Shop account (we'll need your email address) and process the Form 4 for certification.
How the Suppressor Buying Process Works
Choose Your Suppressor or NFA Item
Buy from our in-stock inventory, order through Stonebridge Gunworks, or browse our Silencer Shop dealer link.
Create Your Silencer Shop Account
Manages your purchase, profile, photo, fingerprints, dealer selection, and paperwork dashboard.
Create Your ATF eForms Account
Required for electronic NFA submissions, including suppressor Form 4 transfers and Form 1 applications.
Make Sure Both Accounts Match
Your legal name, address, email, and details should match between Silencer Shop and ATF eForms.
Stonebridge Assigns the Item
Once the item is in your Silencer Shop dashboard, we help you move through the electronic paperwork and certification.
Certify Your eForm 4
Certify and digitally sign remotely through Silencer Shop's Full Auto service, using your ATF eForms User ID and 4-digit PIN. Your User ID is not your email address.
