Lantac M-SPEC 556 5.56mm Direct Thread Suppressor – Black | Includes 1/2×28 DT Hub

The Lantac M-SPEC 556 (M-SPEC556S) is a precision-engineered .223/5.56mm suppressor built for serious shooters who demand performance, durability, and long-term reliability. Machined from 17-4 Stainless Steel in H900 condition, this suppressor delivers outstanding corrosion resistance and an extended service life — whether you’re running it on a carbine, SBR, or a dedicated precision rifle.

The M-SPEC556S features a tubeless baffle design that is 360° full-penetration laser welded, minimizing thermal stress and distortion during manufacture for a stronger, more consistent assembly. Its larger baffle volume contributes to enhanced noise suppression, and the unit has been independently tested to 130dB per MIL-STD-1474E standards. It is full-auto rated with adequate cooling intervals between magazines, making it a capable option for high-volume shooters and duty applications alike.

Each suppressor ships standard with a 1/2-28 UNEF direct thread HUB adapter, which is compatible with any standard 1.375×24 TPI mounting system for added versatility. The HUB adapter can be installed and removed using a standard armorer’s wrench barrel nut tool — no specialized equipment required.
