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.

* PROOF drop-in barrels are designed to fit Ruckus actions with the 'Recessed' bolt nose option only and will not be compatible with actions that have cone, flat, or control round feed bolts.
