Proof Research Barrel for Sig Sauer Cross Features The Proof Research Pre-Fit Sig Cross Barrel comes equipped with the correct barrel extension for the Sig Sauer Cross platform allowing shooters to swap barrels with confidence and without hunting down separate parts. Its carbon fiber wrap is built from aerospace-grade material impregnated with a proprietary matrix resin cutting up to 64% of the weight found in a traditional steel barrel of similar contour. The improved heat dissipation from the carbon wrap keeps the barrel cooler through strings of fire helping preserve accuracy during extended range sessions. Shooters get a barrel engineered for durability and precision without adding unnecessary bulk to their rifle. At 2 lbs 11 oz the 20 barrel with a 1-in-7.5 twist rate is light enough to improve overall rifle balance while stabilizing 6mm Creedmoor bullets for consistent accuracy at distance. The threaded 5/8x24 muzzle accepts a suppressor or brake giving Cross owners options for managing recoil and report. Proof Research s carbon fiber construction is built to withstand extreme temperature swings and repeated firing without degrading performance. This pre-fit barrel gives Sig Cross owners a straightforward path to a lighter more capable rifle.
