How to choose a suppressor
Three questions decide most of it: what caliber it will shoot, whether it moves between guns, and how much length and weight you’ll carry.
1. Caliber rating
Rate the suppressor at or above the biggest, hottest cartridge you’ll shoot. A .30 cal suppressor handles 5.56, 6.5 Creedmoor and .308; a 5.56 suppressor will not survive a .308.
Shoot a lot of .22? Get a separate rimfire suppressor you can take apart and clean.
| Use | Rating |
|---|---|
| Hunting and precision, several rifles | .30 cal multi-caliber |
| Magnums (300 PRC, .338) | .338 cal, Inconel or steel |
| Rimfire | .22 LR, take-apart |
| Pistol | 9mm or .45, with a booster (Nielsen device) |
2. Mount
Direct thread screws onto the barrel. Lightest and simplest; best when it lives on one gun.
HUB (1.375×24) is an open standard: one suppressor, any maker’s HUB mount or brake. The safe pick if you’re not sure.
Quick-detach systems are fast but tie you to one maker’s muzzle devices.
3. Material
Titanium: about 40% lighter than steel. Best for carrying and for bolt guns.
Stainless steel: tough, affordable, heavier.
Inconel: survives fast strings and magnums. Costs more and weighs more.
4. Length and weight
Longer is usually quieter but moves the balance forward. Most rifle suppressors run 6 to 9 inches and 12 to 22 ounces. Modular ones run long at the bench and short in the field.
5. Real sound numbers
Expect a couple of dB worse than the spec sheet. Hearing protection is still smart for long sessions.
| Gun | Unsuppressed | Suppressed |
|---|---|---|
| .22 LR rifle | ~140 dB | 110–120 dB |
| 5.56, 16″ | ~165 dB | 135–142 dB |
| .308, 20″ | ~165 dB | 130–140 dB |
| 9mm pistol | ~160 dB | 125–135 dB |
Typical ranges from published maker specs and independent tests.
