Daystate Blackwolf Onyx Custom SUBMOA X flute barrel

Mechanical Trigger. Slug Power. No Compromises.

The Blackwolf Onyx is a purpose-built slug rifle for shooters who want real trigger feel and real power.

We replaced the electronic system with a Feinwerkbau mechanical match trigger, giving you a true glass-rod break and total control at distance.

Then we pushed the platform harder.

What Makes It Different

Up to 150 ft lbs (.30) capability
25" 1:16 twist X-fluted barrel for heavy slug stability
Voluma Max power system for high airflow and consistency
Built specifically for 40gr (.22), 50gr (.25), 65gr (.30) slugs

Custom SUBMOA Slug Barrel

1:16 SUBMOA X-Fluted Barrel System

No Compromise. Built for Slugs.

The Feinwerkbau Advantage

Sourced from the world of Olympic 10m precision, the Feinwerkbau mechanical Blackwolf Onyx trigger offers a level of adjustment and feel that is simply unavailable in standard production PCPs. It is the ultimate interface for the shooter who knows that at 150 yards, a perfect trigger pull is the difference between a hit and a miss.

SUBMOA X-flute Slug Barrel

This is not a factory barrel.

The Blackwolf Onyx runs a 25" custom 1:16 twist barrel, engineered specifically for heavy, high-BC slugs at elevated power levels.

Cut Rifled → consistent, precise groove geometry
Hand Lead Lapped → ultra-smooth bore, reduced friction, maximum consistency
1:16 Twist Rate → stabilizes heavy slugs where standard barrels fail
X-Fluted Design → increases rigidity, improves cooling, and kills harmonic vibration

Result:

SUBMOA accuracy from a high-power platform that typically sacrifices precision

No shortcuts. No compromises.
This system is built to hold zero, shot after shot, at power levels most rifles cannot control.

This is not a pellet gun trying to shoot slugs, this is a slug gun that can shoot pellets!!!
