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 Defiance Ruckus Pre-Fit barrels exemplify our founders’ pursuit of relentless excellence.
PROOF Research pre-fit carbon fiber & steel barrels for the Defiance Ruckus are to be installed in a simple operation requiring few specialized tools. Our pre-fit barrels are chambered and threaded for a simple install that require only a few specialized tools. Simply torque your barrel on, double check headspace with proper gauges and head to the range! Unprecedented accuracy and performance - it does not get much better than our Defiance Ruckus carbon fiber & steel pre-fit barrels.
