Lone Peak Arms PXT Pre-Fit Barrels

PROOF Research pre-fit carbon fiber & steel barrels are designed to fit the Fuzion, Fuzion Ti, Razor & Razor Ti actions from Lone Peak Arms. Your barrel will arrive chambered/threaded and ready to be installed in a simple operation requiring few specialized tools. Simply torque your barrel on using the proper action wrench and torque setting, double check headspace with proper gauges and head to the range!

PXT - PROOF Exponential Twist - is a complete rethinking of conventional rifling geometry and twist progression, engineered to reduce engraving force, minimize throat erosion, and create a smoother transition as the projectile engages the rifling.

By dramatically reducing rifling lead angle and smoothing projectile engagement into the bore, PXT technology helps reduce wear, improve consistency, and create less felt torque during firing for improved shooting control and the ability to stay on target more effectively.

DISCLAIMER:
- Some older actions (made before Fall 2019) do not have timed threads and headspace may vary slightly. It is recommended to double check headspace after the barrel is installed.
- Due to variance in actions we do not guarantee the timing and alignment of the barrel engraving to your stock line.
