30SD-K QD Suppressor – Premium Multi-Caliber Silencer for Modern Shooters

The 30SD-K QD Suppressor is engineered for shooters who demand compact size, fast attachment, and exceptional noise reduction under all conditions. Moreover, built with elite CNC engineering and Griffin Armament’s legendary mounting technology, this suppressor delivers performance trusted by professionals, hunters, and tactical shooters alike. As a result, every shot is quieter, smoother, and highly controlled. First, this ensures increased accuracy and comfort during extended sessions.

Why the 30SD-K QD Suppressor Stands Out

Griffin Armament designed this compact silencer based on extensive customer feedback. Many shooters requested a shorter .30-caliber QD option without sacrificing performance or durability. Consequently, the engineering team introduced the 30SD-K, which combines cutting‑edge ECO-FLOW™ baffle technology with the industry-leading GATE‑LOK™ interface.

Furthermore, this model delivers remarkable sound reduction—127dB with 300BLK subsonic, 136dB on 5.56mm, and 138dB with .308. Therefore, shooters experience better recoil control, reduced noise signature, and superior comfort during practice or field use. In addition, it supports multiple calibers, making it versatile for various platforms.

Advanced GATE‑LOK™ Fast-Attach System

One of the strongest advantages of the 30SD-K is its extremely fast and secure mounting system. Griffin’s GATE‑LOK interface is designed for speed, durability, and repeatability. Unlike traditional ratcheting mechanisms that wear out over time, this system maintains flawless alignment shot after shot.

It works seamlessly with:

• USGI‑spec A2 compensators (5.56mm)*

• Griffin’s 30SD and M4SD mounts

• Griffin’s proprietary muzzle devices

Additionally, shooters can quickly swap between rifles without losing zero or accuracy. Each mount is precision-ground to ten-thousandths of an inch, ensuring minimal and repeatable point-of-impact shift. In contrast, other systems often compromise reliability under repeated use. Next, this secure mounting allows rapid deployment in the field, which is crucial for tactical scenarios.

30SD-K QD Suppressor: Technical Excellence Meets Hybrid Performance

ECO-FLOW™ Baffle Technology

This patented internal design optimizes gas flow, reduces blowback, and improves overall shooting comfort. Furthermore, it enhances sound suppression while maintaining rifle reliability—especially for 300BLK, 5.56mm, and 7.62 platforms. For example, shooters can enjoy quieter practice sessions and more controlled tactical operations.

Premium Materials & Construction

The suppressor is built from 17‑4PH stainless steel, a high-strength alloy known for corrosion resistance and heat tolerance. Moreover, each unit undergoes CNC machining, wire EDM processing, TIG fusion welding, and precision bore finishing. As a result, shooters receive a suppressor capable of withstanding harsh conditions without performance loss. In addition, the high-quality construction ensures longevity and minimal maintenance.

Multi‑Caliber Flexibility for Modern Rifles

This versatile .30-caliber QD silencer supports a wide range of rifles and calibers, making it an ideal choice for shooters who own multiple firearms. Compatible with:

• 7.62mm

• 300BLK

• 6.8 SPC

• 5.56mm

Therefore, this multi-platform support reduces the need for multiple silencers. Consequently, shooters enjoy seamless transitions between rifles while maintaining consistent performance. Meanwhile, it enhances tactical readiness and provides versatility across different shooting disciplines.
