How to Buy a Suppressor at BattleHawk Armory
Iowa Resident's Guide to In-Store NFA Purchases
Shop In-Stock Inventory
Step 1
Purchase & Ownership Choice
Visit our showroom to browse Iowa’s largest in-stock inventory of suppressors. Our team will ensure you select the perfect suppressor for your application. During this transaction, you must decide if you are filing as an Individual or a Trust. See the ownership types overview at the bottom of the page to help you decide which is right for you.
Objective Performance Data: Manufacturer spec sheets often lack the real-world context needed for a lifetime purchase. To help you navigate our inventory, we have isolated the variables that matter most—Back Pressure, Sound Signature, and Real-World Functionality.
Step 2
Silencer Shop Account & Kiosk
In-store, you will sign in to or create your Silencer Shop account. We will assist you in capturing your fingerprints and photo at our kiosk. This step gathers all the necessary information and documentation needed to prepare and submit your paperwork to the ATF.
Step 3
ATF eForms Account Registration
Next, you must create an account at eforms.atf.gov. This is a critical step that must be completed before we can certify your paperwork.
IMPORTANT: Your name and address must match exactly on both your Silencer Shop and ATF eForms accounts. We advise our customers to reference their state-issued driver’s license for spelling and formatting when creating both accounts.
SAVE THESE: During registration, you will create a 4-digit PIN and the ATF will email you a system-generated Username. You cannot certify your paperwork without both of these.
Step 4
Trust Execution & Upload (If Applicable)
If you purchased a trust, you must complete the following physical documentation:
- Execute: The documents must be signed, notarized, and witnessed.
- Upload: You must upload the completed paperwork to your Silencer Shop account under Account > Dashboard > Registration Info > Trust.
Note: If you are filing using a trust, the process cannot continue until this step is completed.
