This bolt-action rifle from Weatherby is the Mark V Carbon Compact (MCC01N65RWR4B), chambered in 6.5 WBY RPM. The build uses Weatherby's lighter six-lug action with a 54-degree bolt throw, and pairs a 22-inch BSF carbon-fiber barrel with the factory Accubrake DST muzzle brake for an overall 24-inch barrel length. The rifle ships without open sights, ready to mount an optic.

• Hand-laid raised Monte Carlo fiberglass stock carries a black base with brown, green, and white sponge-pattern accents and a 13-inch length of pull. 
• Trigger guard and receiver carry an OD Green Cerakote finish, while the bolt, bolt knob, and safety are finished in Graphite Black Cerakote. 
• Internal floorplate magazine holds 4+1, and the rifle comes with no open sights for a clean optic mount.

Owners of the Mark V Carbon Compact in 6.5 WBY RPM tend to like the newer Weatherby RPM cartridge for its flatter feel behind the trigger compared to older 6.5mm magnums, and the shorter length of pull draws praise from shooters who found a standard Mark V stock too long. A few note that ammunition for the RPM line is not as widely stocked as more established 6.5mm rounds.

The six-lug Mark V action and carbon-fiber barrel come up often as a strong combination, owners like the reduced weight without feeling like the rifle gives up rigidity. The two-tone Cerakote finish and fiberglass stock hold up well to field use in most accounts, though a couple of owners mention the sponge-pattern accents show wear faster than a plain finish would.

Value opinions are mixed: some owners see the Carbon Compact as worth the premium for the weight savings and the TriggerTech trigger, while others feel a standard-weight Mark V in the same chambering would do the job for less. Aftermarket support for the platform tends to follow the broader Mark V ecosystem rather than anything specific to the Carbon Compact variant.
