Suppressor

A suppressor (also called a silencer) reduces the sound signature and muzzle flash of your rifle by trapping and cooling propellant gases. While they don't make firearms "silent" like in movies, quality suppressors reduce report by 25-35 dB, bringing the sound below the threshold for hearing damage and making shooting more pleasant.

NFA Regulations

Suppressors are regulated under the National Firearms Act (NFA). Purchasing requires:

ATF Form 4 submission through a dealer
$200 tax stamp
Background check and approval (typically 6-12 months)
Registration to you as an individual or to a trust

Check your state and local laws—some states prohibit suppressor ownership.

Mount Systems

Quick-Detach (QD) Mounts: Most popular option. Suppressor attaches to a compatible muzzle device (flash hider, brake, or mount).

Dead Air KeyMo/Xeno: Very popular, secure lockup
SilencerCo ASR: Widely available, good compatibility
SureFire SOCOM: Premium, fast-attach system
Griffin Taper: Simple, lightweight system
YHM Phantom: Budget-friendly option

Direct Thread: Suppressor threads directly onto barrel threads (typically 1/2x28 for 5.56). Lighter and more concentric but slower to attach/remove.

Key Specifications

Caliber Rating: The maximum caliber the suppressor is rated for. A .30 cal suppressor can be used on 5.56, 300 BLK, and .308. Using a suppressor on a larger caliber than rated causes baffle strikes and damage.

Length and Diameter: Affects overall rifle length and handguard clearance. Use first-class components.length_min/length_max and components.outer_diameter for filtering and compatibility checks. Shorter suppressors are more maneuverable but less effective.

Weight: Adds to muzzle weight, affecting balance and handling. Ranges from 10 oz to 20+ oz.

dB Reduction: How much the suppressor reduces sound. 25-35 dB is typical. Remember: 3 dB = 2x perceived loudness.

Full-Auto Rating: Indicates the suppressor can handle sustained full-auto fire without damage. Even for semi-auto, this suggests robust construction.

Selection Considerations

Dedicated vs. Multi-Caliber: A dedicated 5.56 suppressor will be lighter and potentially quieter than a .30 cal can on a 5.56 host. But a .30 cal can works across more rifles.

Mount System: Choose based on what muzzle devices you want to run, and consider if you'll share the suppressor across multiple hosts.

Barrel Length: Some suppressors have minimum barrel length requirements to avoid baffle strikes from unburnt powder.

Tuning Your Rifle: Suppressed rifles run with more back pressure. Consider:

Heavier buffer (H2 or H3)
Adjustable gas block
Enhanced buffer spring

Plan for longer cleaning intervals and potentially more gas to the face.
