The MACK Bros platform offers incredible value and tight machining tolerances, making it a favorite for high-performance custom builds. Our drop-in pre-fits provide tactical rigidity and rapid heat dissipation for backcountry hunters and PRS shooters alike.
Our shouldered pre-fits are engineered to interface perfectly with the MACK Bros receiver face. By replacing a standard steel barrel with our aerospace-grade carbon fiber profile, you drastically improve the harmonic dampening of your rifle while saving critical pounds off your total system weight.
Are these pre-fits shouldered for MACK Bros actions?
Yes, our carbon fiber pre-fit barrels are precisely machined with a shouldered design to match the exact headspace guarantees of the MACK Bros EVO actions, allowing for simple drop-in installation.
