📦 How to Send Your MPX for Conversion

📌 Print and include your order receipt – Orders without a receipt will be returned.

📌 Follow our shipping instructions carefully to ensure a smooth process.
📌 We will process a Form 3 to your FFL.
📌 You will complete your tax stamp and paperwork at your FFL.

🔊 Suppressor Maintenance & Warranty – No Cleaning Needed

✔ Non-serviceable design – Built for 40,000-50,000 rounds before requiring maintenance
✔ Contact us before shipping for servicing – Do not send without prior authorization
✔ DO NOT attempt disassembly – Tampering voids the warranty

💯 Ronin Arms Warranty

⚙️ Installation & Removal – Keep It Running Smoothly

🚨 DO NOT FIRE WITHOUT A SUPPRESSOR 🚨
Serious damage may occur

✔ Ensure your firearm is unloaded before installing/removing the suppressor
✔ Hand-tighten only – Over-tightening can damage threads
✔ Allow suppressor to cool before removal

⏳ Turnaround Time: 4-6 Weeks – Precision Takes Time!

🔹 Every build is crafted with precision – Quality takes time, and we refuse to cut corners.
🔹 We do NOT control ATF wait times – Please be patient, as we have no influence over processing delays.
🔹 Calling for updates will NOT speed things up – In fact, it may slow down the process. Trust us, we’re moving as fast as possible!
🔹 We will process a Form 3 for your suppressor and transfer it to your FFL.
🔹 Your barreled upper receiver will be shipped back to you along with your original barrel.

⚠️ IMPORTANT: SHIPPING NOTIFICATIONS ⚠️
You will receive two separate email notifications when your items ship—one for your suppressor and another for your upper receiver. These notifications come from a third-party system, so please check your spam folder if you don’t see them.
