Silencers/Suppressors
349 products · page 1 of 12
A suppressor (silencer) lowers the report of each shot to protect your hearing; it doesn't make a rifle silent. Suppressors are regulated under the National Firearms Act: you need an approved ATF Form 4 transfer through a dealer before you take one home, and some states don't allow them. Since January 1, 2026 the federal tax on that transfer is $0, but registration and approval still apply.
Choose the caliber and attachment first (direct-thread, or a quick-detach mount for a muzzle device), then compare prices below. Lighter suppressors suit short barrels; full-auto rated ones handle heavy use.

Silencers/Suppressors: common questions
How do I buy a suppressor?
Buy it through a dealer who handles NFA items, file an ATF Form 4 (usually electronically, with fingerprints and a photo), and take it home once it's approved. Some states don't allow suppressors at all.
Do I still need a $200 tax stamp?
The 2025 federal budget law cut the NFA tax on suppressors to $0 starting January 1, 2026, but you still need an approved Form 4 before you take possession. Check current ATF guidance.
Direct-thread or quick-detach?
A direct-thread suppressor screws straight onto the barrel: lighter and cheaper, but slower to move between rifles. A quick-detach suppressor locks onto a muzzle device on each rifle and goes on and off quickly.
Can I use a 5.56 suppressor on 300 Blackout?
No. The suppressor's bore must be at least as large as the bullet. A .30-caliber suppressor works on both 5.56 and 300 Blackout with the right mount; a 5.56 suppressor on 300 Blackout is dangerous.
