Built by Otter Creek Labs, the Infinity 556K FDE delivers impressive sound suppression, lightweight construction, and broad mounting compatibility, making it an outstanding choice for AR-15 platforms, short-barreled rifles, and general-purpose 5.56 use.

Compact 5.5-Inch Design

At only 5.5 inches long, the Infinity 556K FDE is one of the more compact options in the 5.56 suppressor category. Its short overall length helps maintain excellent maneuverability on short-barreled rifles and carbines while still providing meaningful sound reduction. The compact size reduces the overall length of the host firearm, improving handling characteristics without sacrificing too much suppression performance.

Flat Dark Earth (FDE) Finish

The Infinity 556K FDE features a professional Flat Dark Earth finish that provides both aesthetic appeal and functional benefits. The FDE coating offers excellent corrosion resistance and a non-reflective surface that reduces glare in bright environments. This finish is ideal for users who want their suppressor to match FDE rifles, handguards, and accessories for a cohesive tactical appearance.

HUB/Bravo 1.375x24 Mounting System

The Infinity 556K FDE is equipped with the industry-standard HUB/Bravo mounting interface featuring 1.375x24 threading. This mounting system offers exceptional compatibility with a wide variety of aftermarket mounts, including direct thread options, quick-detach systems, and various muzzle devices. The HUB mount design allows users to easily switch between different mounting solutions depending on their firearm and preference.

Advanced Sound Suppression Performance

Otter Creek Labs engineered the Infinity 556K FDE to deliver strong sound reduction for 5.56 NATO ammunition. The internal baffle design effectively manages gas flow and pressure, resulting in lower decibel levels at both the muzzle and shooter’s ear. This makes the suppressor particularly effective at reducing audible report and felt recoil, improving shooter comfort during extended range sessions or training.
