PROOF Research is advancing barrel technology with its new exponential twist PXT barrels.

Rifle barrel technology has been relatively stable for a long time, but PROOF Research may have just changed that. The company’s new PXT barrels, standing for PROOF Exponential Twist, are introducing a seemingly simple change to barrel design that could offer a big improvement to performance and lifespan.

While traditional barrel designs use constant-twist rifling, PROOF PXT barrels instead use a progressively changing twist profile. PROOF says that this reduces initial bullet stress, helps maintain rotational stability and prolongs barrel life while improving consistency and performance. As modern high-pressure, high-velocity cartridges gain popularity, accelerated barrel wear and bullet deformation are only becoming bigger concerns, but PXT barrels should help solve those issues.

Brandon Hulzebosch, director of sales and marketing, said this about the new barrels:

PXT is a complete redesign of how the bullet engages the rifling during initial rotation. As the industry advances and ammunition continues to evolve toward higher pressures and performance, we set out to address the technological gap between current barrel systems and where ammunition is headed … PXT gives shooters smoother, more controlled engagement that translates into greater consistency and improved performance. We are excited to be at the forefront of modern technology that will redefine barrel performance across the industry.

PROOF Research PXT barrels are currently being offered as bolt-action blanks, AR-style barrels and select pre-fit models with more options on the way. You can also get a PXT barrel in a complete rifle build with the PROOF Elevation FDX and Elevation MTR.
