Yhm Turbo K-Rb 5.56Mm Suppressor W/Flash Hider

The Yankee Hill Machine Turbo K-RB 5.56mm suppressor with flash hider delivers serious noise reduction and recoil management for AR-15s and other modern rifles. Purpose-built for shooters who demand reliability in high-round-count sessions—whether that's tactical training, competition, or duty use—this suppressor combines a tubeless design with full-auto capability and the kind of engineering that's kept YHM at the top of the suppressor game for decades. At 8.7 ounces (11.5 ounces with adapter) and 4.6 inches long, it strikes a practical balance between performance and handling.

The Turbo K-RB uses heat-treated 17-4 stainless steel construction with an Inconel 718 blast baffle, materials chosen specifically to withstand sustained rapid fire and thermal stress. That tubeless design reduces blowback compared to older designs, keeping your face and optics cleaner during extended shooting sessions. The suppressor threads to the standard 1.375-24 HUB interface, opening up compatibility with a wide range of mounting systems and muzzle devices from the industry's leading makers.

What ships in the box: the suppressor itself, a 1/2 x 28 Phantom Q.D. quick-disconnect adapter, a Phantom Q.D. flash hider, and YHM's proprietary mounting accessories. The quick-disconnect system means you can swap the suppressor on and off without tools—handy for moving between rifles or when you need to stow the can. The notched rim and tri-port end cap aren't just good looks; they're functional design that's become a YHM signature.

Rated at 138 decibels and approved for a minimum 10-inch 5.56 NATO barrel, this is a suppressor engineered for serious use. It's been tested and recommended by the National Tactical Officers Association, a credential that matters to professionals and serious sport shooters alike.
