Stag Arms 20" 5.56 Chrome-Lined/Phosphate HBAR 1:7 Rifle Length Barrel w/ FSB - $129.95

Description

The Stag Arms 20″ 5.56 HBAR barrel is built for shooters who want classic rifle-length performance with modern durability. A chrome-lined bore and chamber help resist corrosion and reduce fouling for easier maintenance, while the phosphate exterior adds wear protection for hard-use conditions. The heavy barrel (HBAR) profile improves stability and heat management, supporting tighter groups during longer strings and better consistency at distance.
This barrel includes a pinned front sight base (FSB) for traditional builds and dependable alignment, paired with a rifle-length gas system for smooth cycling. With a 1:7 twist, it’s optimized for heavier 5.56 projectiles (commonly 62–77gr), and the 1/2×28 muzzle threads keep it compatible with common muzzle devices.
