The PROOF Research 10/22 .22LR 16.1" bull barrel with 1:16 twist combines carbon fiber construction with match-grade accuracy for precision rimfire shooters and competitive 22 competitors. This is a gunsmith-grade barrel blank—ready for threading and chambering by your smith—that trades the weight and bulk of traditional steel for a lighter, stiffer platform without sacrificing the repeatability that serious .22 shooting demands. Whether you're building a custom target rifle, upgrading a bolt-action 10/22 platform, or chasing sub-MOA groups at distance, a carbon-wrapped rimfire barrel from PROOF Research delivers the durability and performance that matters when every shot counts.

Carbon fiber barrels have earned a reputation among long-range and competitive shooters for their strength-to-weight ratio and resistance to the elements. PROOF Research's execution sets them apart: their carbon-wrapped design is significantly lighter than traditional steel barrels while maintaining the rigidity needed for match-grade performance. The engineered construction helps manage barrel vibration and heat, supporting the consistency that precision rifle work requires. Because the barrel arrives unthreaded and unchambered, you have the flexibility to work with your gunsmith on the exact configuration—muzzle threading, chamber finish, and fit—that your build demands.

The 16.1" length and 1:16 twist rate are tailored for standard and high-velocity .22LR ammunition, balancing velocity, handling, and the barrel harmonics that affect accuracy. For shooters building or upgrading a 10/22-platform rifle, this barrel offers a significant step up in material science and engineering over factory options. PROOF Research barrels are known for durability in the field and on the range—carbon fiber resists corrosion and cosmetic damage far better than bare steel, reducing maintenance and keeping your rifle ready to shoot.
