Description

PROOF Research pre-fit carbon fiber & steel barrels for the Impact Precision 737R, 787R, and NBK/777R are to be installed in a simple operation requiring few specialized tools. These barrels come chambered and threaded for an easy install.

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.

 

Features:

  • Long-Lasting: Excellent erosion wear characteristics and corrosion resistance.
  • Extreme Pressure Resistance: An optimum combination of high tensile strength along with requisite toughness to withstand extreme chamber pressures encountered during firing.
