SIG NG556C-QD
$1,399.00
The SIG NG556C-QD delivers top-tier suppression in a compact, lightweight design built for shooters who want maximum performance without added bulk. Its 3D-printed core improves strength while reducing weight, allowing better gas flow and efficient sound reduction. The suppressor’s low-blowback design helps keep your AR-15 or other direct-impingement rifles running clean by minimizing port noise and excess gas. This makes long shooting sessions far more comfortable.
The Clutch-Lok quick-detach system ensures fast and secure mounting, keeping accuracy consistent and the suppressor locked firmly in place, even in harsh conditions. Despite its small size, it provides impressive decibel reduction and excellent durability thanks to its Inconel construction and Black Cerakote finish. At only 5.2 inches and 14.6 ounces, it adds minimal length to your rifle while delivering reliable, modern suppression. Ideal for shooters who value mobility, control, and clean performance.
Compact Next-Generation Suppressor Design
The SIG NG556C-QD brings modern suppressor engineering to shooters who need a compact and efficient solution for 5.56 rifles. This model leverages SIG’s Next Gen technology to create a high-performance silencer that stays lightweight without sacrificing capability. Its shorter profile adds very little length to the rifle while still providing noticeable sound and flash reduction. This makes it ideal for maneuverability, close-quarters work, and fast transitions between targets.
Low-Blowback System for Cleaner Shooting
This compact suppressor uses a redesigned internal flow system that vents gases more efficiently. By reducing backpressure, shooters experience far less blowback at the ejection port. This means cleaner operation, fewer fumes near the face, and reduced port noise during rapid or sustained fire. The technology works exceptionally well on direct-impingement platforms like the AR-15, where backpressure can normally affect reliability and comfort.
Advanced 3D-Printed Core Structure
A standout feature of this suppressor is its monolithic 3D-printed core. This modern construction method improves durability, reduces weight, and allows SIG to build internal geometry that enhances performance. The unique structure improves gas management and contributes to better decibel reduction in a smaller footprint. This innovation also increases the suppressor’s longevity, making it a dependable tool for both training and duty use.
Secure and Fast Clutch-Lok Mounting System
Shooters benefit from the Clutch-Lok quick-detach system, which delivers rapid attachment with an exceptionally solid lockup. This system prevents the suppressor from loosening during firing and maintains consistent point-of-impact alignment. Whether you’re swapping between hosts or preparing the rifle quickly, the mounting interface remains intuitive and dependable.
Designed for Versatility on 5.56 Platforms
Built for rifles like the AR-15, this suppressor excels in situations requiring mobility and precision. Its short length keeps rifles easy to handle, especially when moving through tight spaces or running dynamic courses. The reduced weight allows for better balance, helping shooters maintain stability and accurate follow-up shots.
Durable Build for Harsh Conditions
Made from Inconel and finished with Black Cerakote, the suppressor stands up to heavy use and extreme temperatures. It resists wear from high-volume shooting, maintaining structural integrity even during demanding training sessions. The compact body also makes it an excellent choice for shooters who want durability without unnecessary size.
Technical Specifications and Included Components
The suppressor measures 5.2 inches in length and weighs 14.6 ounces, making it one of the most compact options in its class. It is optimized for 5.56 caliber rifles and arrives with an owner’s manual for quick setup. Its design ensures long-term reliability and impressive suppression in a small, efficient package.
