Bighorn Origin Pre-Fit Barrels

DESIGNED FOR THE ENTHUSIAST

When PROOF Research was formed in 2012, our vision was both simple and extraordinary. Our truly innovative founders envisioned a company that would apply advanced science, new technologies, aerospace-grade materials and manufacturing excellence to produce a new class of products that would truly revolutionize the firearms industry. Our barrels, both carbon fiber and steel, exemplify our founders’ pursuit of relentless excellence. Whether your preference is for carbon fiber or steel, you can expect the finest rifle barrel in the industry.

Our rifle barrels are available for both bolt-action and AR-style rifles in a variety of calibers, lengths and twists. Your bolt-action barrel will arrive ready for thread and chamber by your gunsmith. Your AR-style barrel will arrive threaded and chambered.
