7.62 and .308 suppressors, in stock. This is the caliber the whole suppressor industry is measured against. Manufacturers publish their .308 numbers because it is the cartridge everyone can compare, and a can that performs well here will handle almost anything smaller in the safe.
Every suppressor below accepts a .308 inch bullet, which covers 7.62×51 NATO, .308 Winchester, .30-06, .300 Blackout and every smaller rifle caliber you own. What separates them is weight, length, mount, and how much heat and pressure they are rated to take. The buyer guide under the products walks through each of those decisions.
Pair it with our .308 Win ammunition, or check the full caliber index if you are stocking several rifles at once.

Why .308 is the benchmark caliber for suppressors
When a manufacturer quotes a sound reduction figure, it is almost always measured on a 7.62 or .308 rifle. There is a practical reason for that. 7.62x51 sits in the middle of the rifle world for pressure, gas volume and heat, so a suppressor rated and tested here has been proven against a realistic worst case for most shooters. It also means the published numbers on this page can actually be compared with one another, which is rarely true across calibers. Match the can to a load from our blackout ammo range.
For buyers, the useful consequence is simple: a .308 rated can is the safest single purchase in a mixed safe. It will handle 7.62x51 NATO, .308 Winchester, .30-06 Springfield, .300 Blackout, 6.5 Creedmoor, 6mm ARC, .223 and 5.56, and .22 LR. The one thing it will not handle is 8.6 Blackout, which fires a .338 bullet and needs its own .338 rated suppressor.
Bolt gun or gas gun, and why it changes the can
The rifle matters more than most buyers expect.
On a bolt action, nothing cycles, so the suppressor only has to be quiet and durable. You can run a lighter can, and a direct thread mount is perfectly reasonable because the rifle is not moving gas backwards at your face. This is where the quietest, simplest setups live.
On a gas gun, an AR-10 or similar, the suppressor raises back pressure, and that back pressure travels down the gas tube. The rifle cycles harder and faster, the bolt unlocks earlier, more gas comes out of the ejection port and the charging handle, and the whole thing runs dirtier and hotter. That is not a fault, it is physics, and there are three standard answers: an adjustable gas block, a heavier buffer, or a low back pressure suppressor design. Most owners of a suppressed .308 gas gun end up using at least two of the three.
| Consideration | Bolt action | Gas gun (AR-10) |
|---|---|---|
| Back pressure | irrelevant | the main design factor |
| Gas in the face | none | common without tuning |
| Mount | direct thread is fine | quick detach usually preferred |
| Weight tolerance | higher, rifle is already heavy | lower, it hangs off a long barrel |
| Tuning needed | none | gas block or buffer, often both |
Barrel length and thread pitch
Most .308 and 7.62 rifles use a 5/8x24 thread, which is effectively the standard for the caliber. Where people get caught out is mixing rifles: many 300 Blackout and 5.56 barrels use 1/2x28 instead. A quick detach system solves this cleanly, since you fit the correct muzzle device to each rifle and the suppressor itself never changes.
Check the minimum barrel length in the manufacturer's specification before ordering. Short barrels raise the pressure and temperature at the muzzle, and a can rated for a 16 inch .308 is not automatically approved for a 10 inch one.
Frequently asked questions
Is a 7.62 suppressor the same as a .308 suppressor?
Yes, for buying purposes. 7.62x51 NATO and .308 Winchester use the same .308 inch bullet, and manufacturers use the two names interchangeably in suppressor listings. The small pressure difference between the two cartridges does not change suppressor selection.
Can I use a .308 suppressor on 5.56 or .223?
Yes. The bore is larger than the bullet, so it is safe. You give up a few decibels compared with a dedicated 5.56 can, which most owners accept in exchange for covering several rifles with one purchase.
Can I use it on 8.6 Blackout?
No. 8.6 Blackout uses a .338 bullet, which is larger than a .30 caliber bore. It requires a .338 rated suppressor. This is the one compatibility mistake on this page that damages equipment and endangers the shooter.
How quiet is a suppressed .308?
Hearing safe with a good can, typically in the low 130s in decibels at the ear with supersonic ammunition, down from roughly 165 unsuppressed. Comfortable and civilised, but not silent, because the sonic crack of the bullet is untouched by any suppressor.
