20'' Hybrid Contour, Rifle Gas System, 223 Wylde

The 20" Hybrid Contour, Rifle Gas System, 223 Wylde barrel from Criterion Barrels Inc is a precision-engineered solution for AR-15 builders and shooters who demand accuracy, reliability, and practical performance across diverse shooting disciplines. This rifle-length gas system configuration delivers the balanced handling characteristics operators require for everything from 3-gun competition to tactical training and defensive applications.

Criterion's reputation for chamber consistency and bore quality makes this barrel a trusted choice for those who understand that accuracy begins at the foundation—the barrel itself. Built with a hybrid contour design, this 20-inch barrel optimizes the balance between weight and rigidity—a critical consideration in field rifles where every ounce matters but zero shift cannot be compromised. The 1-in-8 twist rate stabilizes a full range of 223 Wylde ammunition, from lightweight 55-grain loads to heavy match-grade 77-grain projectiles, offering versatility without sacrifice.

The .720" muzzle diameter and 1/2x28 threading accommodate standard tactical accessories, suppressors, and compensators, while the 223 Wylde chamber provides superior accuracy potential and accepts both 5.56 NATO and 223 Remington ammunition safely. At 2.35 pounds, the barrel contributes minimal overall system weight while maintaining the rigidity necessary for sub-MOA performance at distance. This barrel excels for shooters building precision AR-15s intended for various applications.
