PROOF Research pre-fit carbon fiber & steel barrels for the Impact Precision 737R and 787R are to be installed in a simple operation requiring few specialized tools. These barrels come chambered and threaded for an easy install - torque on, ensure headspace with proper gauges and head to the range! Shot for shot accuracy and performance - there is simply no better choice for the Impact Precision actions than our carbon fiber & steel pre-fit barrels.
* All shouldered pre-fit barrels are guaranteed for headspacing.
* Due to variance in actions we do not guarantee the timing and alignment of the barrel engraving to your stock line.
* Barrels are specific to the action type/length and are not interchangeable.
Up to 64% lighter than traditional steel barrels of similar contour.
Improved heat dissipation for cooler and longer lasting barrels.
Wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin.
Excellent erosion wear characteristics and corrosion resistance.
An optimum combination of high tensile strength along with requisite toughness to withstand extreme chamber pressures encountered during firing.
