MudGhost M4 12.5″ 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 both subsonic stealth and supersonic reach, it delivers devastating terminal performance in the brush, through the timber, and across the field.

At its core is a 12.5” precision barrel mated to an 8” titanium suppressor, fully integrated for perfect balance, minimal signature, and brutal efficiency. Whether you’re stacking pigs or dropping whitetail, the .338 ARC delivers heavyweight energy with superior downrange control—without lighting up your position or wrecking your hearing.

The 1:8 twist maximizes stability for a wide range of bullet weights. The 15” ZeroLok ARCA handguard locks down your shooting position with full-length ARCA rail, M-LOK slots, and QD sling cups—ready for bipods, tripods, and all the glass or gear your hunt demands.

A crisp 2.5 lb trigger, short-throw ambi safety, and vertical grip deliver surgical control and fast transitions, while 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 is fully amphibious—built to fire in rain, snow, mud, or immediately 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.
