Overview

The Yankee Hill Machine Turbo K represents the best value proposition in the compact 5.56 suppressor market. At just 4.75 inches long and 8.83 ounces (11.7 oz with QD mount), the Turbo K is designed for shooters who prioritize maneuverability and weight savings while maintaining hearing-safe sound levels. The unique tubeless design uses only three baffles made from heat-treated 17-4 stainless steel with a 718 Inconel blast baffle.

With an average sound pressure level of 134-138 dB on 16-inch AR barrels using 55-grain ammunition, the Turbo K stays within the 140 dB hearing-safe threshold while remaining remarkably compact. It completely eliminates blast and concussion while greatly reducing muzzle flash. The suppressor's tube features the industry-standard 1.375x24 thread pattern, providing compatibility with dozens of mounting systems from Dead Air, Q, SilencerCo, and others.

As an NFA-regulated item, the Turbo K requires ATF Form 4 approval and a $200 tax stamp. At an MSRP of $534 (often found below $400), it delivers exceptional performance-per-dollar value. The full-auto rating and robust construction make it suitable for defensive and hard-use applications.
