PROOF Research offers pre-fit barrels made of carbon fiber and steel for the Defiance Ruckus. Installing these pre-fit barrels can be done easily with minimal specialized tools needed. The barrels are chambered and threaded for a straightforward installation process. Once the barrel is torqued on, headspace can be double checked with the appropriate gauges and then it's ready to hit the range. Featuring unparalleled accuracy and performance, the Defiance Ruckus carbon fiber and steel pre-fit barrels are the ultimate choice.

Additionally, PROOF Research's carbon fiber barrels are an impressive 64% lighter than traditional steel barrels. This translates to improved heat dissipation, resulting in cooler, longer-lasting barrels. The barrels are wrapped in aerospace-grade carbon fiber that is impregnated with a proprietary matrix resin to provide high-strength and durability.

Please note that the PROOF drop-in barrels are intended for use with Defiance Ruckus, Tenacity and Anti actions that have 'Recessed' bolt nose option only. They will not be compatible with actions that have cone, flat, or control round feed bolts.
