OSS Suppressor Wait Times (2026)
Wondering how long it takes to get a OSS suppressor approved? The wait time depends on the ATF's national queue, not on which brand of suppressor you buy. Once you file your Form 4, your application goes into the same queue regardless of whether you bought a OSS can, a SilencerCo, or a YHM. The current wait times are at the top of this page.
About OSS
OSS uses a different flow-through design that aims to reduce backpressure. The HXM and BPR are their main rifle models.
Key OSS products
OSS's most popular product lines include: HXM, BPR, M4. Each is designed for different use cases (rifle vs pistol, hard-use vs precision, multi-cal vs single-cal), and the ATF approval wait time is the same for all of them.

The wait time above is what you can expect when you file a Form 4 for a OSS suppressor. It applies to all of their products equally — ATF doesn't have separate queues per brand.
How to file for a OSS suppressor
- Pick the specific OSS model you want. OSS makes HXM, BPR, M4 and the right one for you depends on caliber, host firearm, and use case.
- Buy through a dealer. Silencer Shop and Silencer Central both stock OSS suppressors and offer eForms filing (faster).
- Submit your Form 4 through the dealer's eForms kiosk or paper-file through the ATF.
- Wait. Average wait is shown above; the OSS will ship to your local FFL/SOT after approval.
OSS vs other brands
Wait time isn't the differentiator between OSS and other brands — all silencers go through the same ATF queue. The differences are in sound suppression, weight, length, mounting system, materials, and warranty. See our suppressor guide for help choosing.
FAQ: OSS suppressors
How long does it take to get a OSS suppressor approved?
See the current wait time at the top of this page. It's the same as for any other brand because ATF processes all Form 4s in a single national queue.
Do I need a trust for a OSS suppressor?
You can file as either a trust or an individual. Trust filings take a few days longer to process because the trust adds an extra review step. See trust vs individual.
Can I buy OSS suppressors online?
Yes. Silencer Shop, Silencer Central, and most major online NFA dealers stock OSS suppressors. You still need to file the Form 4 through a dealer — you can't buy directly from the manufacturer as an individual.
What's the most popular OSS suppressor?
Among OSS's lineup (HXM, BPR, M4), sales rankings shift year to year. Check the latest OSS catalog or ask a dealer which models are moving fastest in your caliber.
