While firing the shooter can be distracted because of any trifle that negatively affects the result. Loud noise can be one of such bothersome factors. The centerfire rifle .308 in 24-in barrel features 156.2 dB, which can cause damage to shooters and possibly those who stand near them.

Suppressors are not in vain called silences, emphasizing their main function. The muffle devices are designed to decrease the range and velocity of the projectile gasses, shooting up from the muzzle.

Why Do You Need .308 Suppressor?

To the point of hearing safety, it’s better to install a suppressor on a .308 rifle. Depending on ammo (usual rounds or subsonic ones), barrel length, and environmental conditions, sound suppression can differ less than 3 dB.

The suppressed rifles can be used everywhere: at hunting, at the range, or while sportive shooting, allowing the participants to hide from opposing players. The silences muffle the shot sound, protecting your ears and nearby ones. It’s not a joke as lawsuits can be applied for gunfire noise that causes hearing loss.

FAQ

Do suppressors reduce accuracy?
The silencer doesn’t decrease accuracy, it attenuates the shooting noise, allowing the shooters to focus on the aim. If the suppressor is properly mounted, it makes less muzzle climb and concussive effect, even improving accuracy.
How quiet are silencers in real life?
Even after suppressing shooting noise (approximately 14.3-43 dB), the gunshot sound exists, the level of a decibel can vary, depending on used rounds (a subsonic or usual one), the length of the barrel, and silencer.
Do I have to carry my tax stamp with my suppressor?
Yes, the shooters need always take a tax stamp with the silencer, to show it on the ATF agents’ demand as proof of the registration.
How long do suppressors last?
Dependable rifle silencers deliver a service life of around 30,000 bullets or more. The sturdier materials are used, the longer the full-automatic fire period.
Are homemade silencers illegal?
Home-made suppressors must be registered to be legal. The legalization process is the same as for legal short-barreled rifles (SBS and SBR) and shotguns; before building should be submitted to background verification. A $200 tax stamp should be received (filling Form 1 under the National Firearms Act) and carried whenever shooters want to shoot with this suppressor.

Conclusion

The suppressor reduces decibels (from 14 to 45 dB). The final quietness of silenced firearms during the shooting can be different, depending on suppressor brands, the barrel length, and used rounds (subsonic or usual ones).

Remember even reliable silencers need proper maintenance to keep high performance.

.308 caliber suppressors are considered high-pressure ones; it helps them blast out the old carbon, leaving a light new carbon coating with every shot, so no need to clean such rifle suppressors.
