YHM BAD LARRY .338 SUPPRESSOR
The Yankee Hill Machine Bad Larry .338 suppressor is built for shooters who want serious sound reduction on heavy-hitting magnum rifles without the weight penalty. Whether you're running .338 Lapua Magnum, 8.6 Blackout, or other large-bore cartridges, this direct-thread suppressor delivers the performance you need for long-range hunting, precision rifle competition, or tactical work—all while staying light enough to make a real-world difference on your gun.
YHM engineered the Bad Larry around reliability and durability: the core is heat-treated 17-4 PH stainless steel with Stellite/Cobalt 6 blast baffles, so it can handle the brutal pressures and temperatures of magnum rifle rounds without degradation. At 17 ounces and just over 7 inches long, it's compact enough to keep your sight radius manageable on short-action setups, and the 1.375-24 HUB mounting threads open up compatibility with YHM's full ecosystem of quick-detach and mounting accessories if you decide to swap it between rifles.
Rated for full-auto fire and delivering 136 dB of sound suppression, the Bad Larry doesn't compromise on effectiveness—it's a working silencer for hunters and shooters who refuse to run loud or pick between performance and practicality. The package ships with a 5/8-24 direct-thread adapter, two suppressor wrenches, and YHM's no-nonsense warranty backing, so you can mount it and get to work the same day.
