Suppression on the modern battlefield demands more than a quiet report — it requires materials and designs that survive sustained combat conditions while protecting the shooter from signature and toxic gas exposure. For units and operators who need a durable, repeatable, and low-signature solution, the right suppressor can change mission outcomes.

SIG SAUER SPEARQD 6.8mm delivers military-grade performance built to the exact specifications of suppressors fielded by the U.S. Department of Defense. The NG68SPEAR-QD’s rugged monolithic core construction is purpose-built for extreme durability, including sustained fire from belt-fed machine guns, while the advanced LO-TOX design minimizes toxic gas exposure at the ejection port.

Rugged construction and field-proven features

The suppressor uses a monolithic core for structural integrity under high cyclic stress. This single-piece approach resists erosion and loosening that can plague multi-piece designs during prolonged automatic fire. The flash-reducing end cap significantly lowers visible muzzle flash, an essential feature for night operations and signature management. SIG’s Clutch-Lok QD mounting system provides fast, secure, and repeatable attachment — a must for dynamic weapon setups where a consistent point of impact and quick swap capability are required.

LO-TOX safety and materials

The LO-TOX architecture reduces the volume of toxic gases expelled at the ejection port, improving shooter safety and comfort during extended firing sequences. The offered Inconel construction delivers heat resistance and long-term durability in high-temperature environments, supporting the suppressor’s DoD-grade intent.

Applications and the 6.8mm advantage

Chambered for 6.8mm use, this suppressor complements rounds designed for improved terminal performance and extended effective range compared to smaller intermediate calibers. That makes it suitable for combat, designated marksman roles, and training scenarios where suppressed signature and consistent ballistic performance are priorities. At a price point of $1699.99, the SPEARQD represents an investment in durability and DoD-spec performance for professional users.
