HQS Special Sound Moderator

The HQS Special rifle suppressor is a premium, heavy-duty silencer engineered specifically for large caliber and magnum rifles, including the demanding .338 Lapua Magnum and .300 RUM (Remington Ultra Magnum). Built for professional shooters, hunters, and military applications, this suppressor delivers exceptional sound reduction, recoil control, and long-term durability.

Advanced Dual-Stage Single Core Technology

At the heart of the HQS Special is a patented single-core suppressor design divided into two functional chambers, each operating via a distinct gas management principle. This innovative dual-stage baffle system maximizes sound attenuation while the integrated patented pressure release technology significantly extends the suppressor’s service life — even under the extreme pressures generated by magnum caliber cartridges.

Superior Sound Suppression – 34+ dB Noise Reduction

Achieving a minimum of 34 dB sound reduction, the HQS Special is tested and certified to MIL-STD-1474D military standards — the gold standard for suppressed firearm acoustic measurement. Whether used for precision long-range shooting, big game hunting, or tactical operations, this suppressor delivers reliable, consistent noise attenuation shot after shot.

Maximum Recoil Reduction for Magnum Rifles

Designed to handle the brutal recoil of the world’s most powerful rifle cartridges, the HQS Special provides maximum recoil reduction for improved shooter comfort, faster follow-up shots, and enhanced accuracy — critical advantages when shooting .338 Lapua, .300 RUM, or .375-caliber rifles.

Compatible with Semi-Automatic and Bolt-Action Magnum Rifles

The HQS Special is fully compatible with semi-automatic rifles and supports a wide range of calibers up to .375 / 9.3mm, making it one of the most versatile large bore suppressors available. Multiple thread options ensure compatibility with virtually any barrel configuration.
