MudGhost M4 10.5″ Integrally Suppressed .338 ARC Rifle

Built for the Hunt. Born to Drop Beasts.

The MudGhost M4 in .338 ARC is a purpose-built predator—engineered from the ground up as a dedicated, integrally suppressed hunting rifle. Compact, powerful, and optimized for subsonic stealth or supersonic reach, it delivers devastating terminal performance in the brush, through the timber, and across the field.

At its core is a 10.5” barrel mated to an 8” titanium suppressor, fully integrated for unmatched balance, minimal signature, and brutal efficiency. Whether you’re stacking pigs or dropping whitetail, the .338 ARC delivers heavyweight energy with precision control—without lighting up your position or wrecking your hearing.

The 1:8 twist wrings maximum stability from a wide range of bullet weights. The 13.5” ZeroLok ARCA handguard provides rock-solid support with full-length ARCA rail, M-LOK slots, and QD sling cups—ready for bipods, tripods, and all the glass or gear you want to run.

A crisp 2.5 lb trigger, short-throw ambi safety, and vertical grip deliver surgical control and fast transitions. M-LOK heat shield pads protect your hands from suppressor bleed-off during extended stalks or rapid follow-ups.

Powered by 51Fifty’s patented HydroBuffer system, the MudGhost M4 is fully amphibious—built to operate flawlessly in rain, snow, mud, or after complete water submersion. Hunt how you want, where you want—without compromise.

This isn’t a battle rifle. It’s not a DMR. It’s a savage tool of the hunt—tuned for real-world impact where it matters most.
