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 qualifying Stonebridge or Silencer Shop orders.
Outside NFA Transfers
If you purchase an NFA item from another outside source and transfer it to Stonebridge Gunworks, the outside NFA transfer fee is $80.
Active Duty Military and Law Enforcement Officers receive the reduced outside NFA transfer fee of $40.
How the Suppressor Buying Process Works
1. Choose Your Suppressor or NFA Item
You can purchase from our in-stock suppressor inventory, order through Stonebridge Gunworks, or browse through our Silencer Shop dealer link.
2. Create Your Silencer Shop Account
Your Silencer Shop account manages your purchase, profile, photo, fingerprints, dealer selection, and paperwork dashboard.
3. Create Your ATF eForms Account
Your ATF eForms account is required for electronic NFA submissions, including suppressor Form 4 transfers and Form 1 applications.
4. Make Sure Both Accounts Match
Your full legal name, address, email, and personal details should match between Silencer Shop and ATF eForms. Small differences can cause delays.
5. Stonebridge Assigns the Item
Once the suppressor is assigned to your Silencer Shop account dashboard, we will help you move through the electronic paperwork and certification process.
6. Certify Your eForm 4
You will digitally certify your eForm 4 using your ATF eForms User ID and 4-digit PIN. Your ATF User ID is not the same thing as your email address.
7. Wait for ATF Approval
After submission, the application is reviewed by ATF. Current estimated processing times can be checked on the official ATF current processing times page.
8. Book Pickup After Approval
Once your approval email is received, book an appointment with Stonebridge Gunworks. At pickup, we will complete the final 4473 transfer and release the approved item.
Create These Two Accounts Before Submission
Most first-time suppressor buyers need two separate online accounts before the paperwork can be completed.
