PROOF Research BBL Bolt 22 Creedmoor 20" Carbon Fiber Barrel for SIG Cross - Drop In

The PROOF Research BBL Bolt 22 Creedmoor 20" carbon fiber barrel for SIG Cross is a drop-in upgrade that transforms your Cross rifle into a lightweight, long-range capable shooter. Built with PROOF's carbon fiber wrap technology, this pre-fit barrel eliminates the guesswork and machine work of traditional barrel installation—simply mount it to your existing Cross receiver and you're ready to shoot. If you're running a Cross and want to add a purpose-built 22 Creedmoor without the hassle of gunsmithing, this is your answer.

The 20-inch length and 22 Creedmoor chambering strike a practical balance for hunters and distance shooters who value maneuverability without sacrificing ballistic performance. The carbon fiber construction cuts weight dramatically compared to steel barrels of the same contour, making a noticeable difference when you're glassing hillsides or hiking into backcountry. That weight savings doesn't come at the cost of durability—PROOF's aerospace-grade carbon fiber wrap and proprietary resin matrix are engineered to handle the heat and stress of serious shooting sessions.

Because this is a drop-in design built specifically for the SIG Cross platform, there's no fitting, no headspace concerns, and no waiting at the gunsmith. You get a hassle-free barrel swap that lets you quickly change calibers or reconfigure your rifle for different seasons or hunts. Whether you're a precision rifle competitor, a long-range hunter, or someone who just likes the flexibility of a modular platform, a pre-fit barrel removes friction from the upgrade process.
