The Ferret 50 is a high-caliber bolt-action rifle developed by Spider Firearms for competition shooting and long-range hunting. It is chambered for .50BMG, .408 CheyTac, and .338 Lapua

The Ferret 50 was crafted as an AR conversion for its high adaptability and customization potential. The stock is made from a polymer, it weighs between 18 and 24lb depending on the caliber, and its barrel length ranges from 18" to 36", again depending on the caliber. It is a single-shot, meaning it has no magazine, internal or external. It can also be finished in either chrome-moly or stainless steel.
One key feature of the Ferret 50 is the fish-gill muzzle-break. This allows the rifle to fire large caliber rounds with controllable recoil but no loss in accuracy.

Ferret 50 SuperComp

The SuperComp Ferret 50 is the competition-level version of the rifle. It can be chambered in all the above mentioned calibers (except .338 Lapua) plus .510 DTC

Ferret 50 Sportsman

Another version of the Ferret 50 is the Sportsman. It is simply a lower-grade version designed for more casual shooters and hunters. It has no significant difference between the SuperComp except for caliber--the Sportsman does not come in .510 DTC but can be chambered for .338 Lapua.
