The Yankee Hill Machine Turbo K-RB is a 5.56mm suppressor designed for shooters who demand reduced sound signature without compromising reliability. Built from heat-treated 17-4 stainless steel with an Inconel 718 blast baffle, this suppressor delivers the durability needed for everything from precision rifle work to sustained automatic fire. The tubeless design is lighter than many competitors and engineered to handle the pressures of modern 5.56 NATO ammunition while keeping a compact profile.
What sets the Turbo K-RB apart is its thoughtful engineering: a notched rim, tri-port muzzle end cap, and integrated 1.375-24 HUB threading give you flexibility in how you mount and configure it. The included 1/2 x 28 Phantom Q.D. adapter lets you mount and remove the suppressor quickly on compatible rifles. Reduced blowback compared to earlier designs means less gas in your face when shooting—a real comfort factor in tactical, hunting, and range scenarios where you're running optics or shooting from positions where you'd normally catch a faceful of propellant gas.
YHM's reputation for precision manufacturing shines here: every component is heat-treated and stress-tested to eliminate weak points. The Turbo K-RB arrives with the Q.D. adapter, a QD flash hider, and a QD muzzle brake, so you can start experimenting with your setup right out of the box. Law enforcement and military end-users have already put their stamp of approval on this platform—NTOA tested and recommended in 2023.
| Caliber | 5.56mm NATO |
| Weight (suppressor only) | 8.7 oz. |
| Weight (with adapter) | 11.5 oz. |
| Length (suppressor only) | 4.6 in. |
| Length (with adapter) | 5.5 in. |
| Diameter | 1.5625 in. |
| Construction Material | 17-4 Ph Stainless Steel / Inconel 718 Blast Baffle |
| Mount Type | 1/2 x 28 Phantom Q.D. HUB adapter |
| Sound Reduction | 138 dB |
| Minimum Barrel Length (5.56 NATO) | 10 in. |
| Rating | Full Auto Rated |
The Turbo K-RB requires a minimum 10-inch barrel for 5.56 NATO and mounts via 1/2 x 28 threads using the included Phantom Q.D. adapter. Any rifle with a 1/2 x 28 threaded muzzle or a muzzle device that accepts 1/2 x 28 adapters will work. The 1.375-24 HUB threading also allows you to explore other mounting options beyond the included adapter.
The suppressor ships with a 1/2 x 28 Phantom Q.D. adapter, a QD flash hider, a QD muzzle brake, and the Turbo K-RB suppressor itself. You can swap the flash hider and muzzle brake depending on whether you prioritize flash reduction or recoil management.
Yes, the Turbo K-RB is full-auto rated and designed for sustained fire. The heat-treated 17-4 stainless steel and Inconel 718 blast baffle are built to handle the extreme pressures and temperatures generated by fully automatic 5.56 NATO fire.
The Turbo K-RB achieves 138 dB sound reduction at the shooter's ear. The suppressor's reduced blowback design also minimizes the gas signature that can cause additional perceived noise when shooting from enclosed positions or behind optics.
