The Proof Research Pre-Fit Sig Cross Barrel, .22 Creedmoor, 20.00" Threaded Barrel, Stainless is a purpose-built drop-in upgrade for the Sig Sauer Cross platform. Featuring a stainless steel core wrapped in aerospace-grade carbon fiber, this 20-inch threaded barrel is engineered to deliver precision accuracy while significantly reducing weight and improving handling.

This .22 Creedmoor pre-fit barrel is ideal for shooters building a lightweight, long-range hunting or precision rifle. The carbon fiber construction promotes better heat dissipation during extended strings of fire, while the 1-in-8 twist rate stabilizes a wide range of modern high-BC projectiles. With its included barrel extension and true drop-in design, caliber changes and barrel upgrades become straightforward and repeatable, reflecting Proof Research’s focus on practical performance and refined barrel technology.
