Aero Precision 16″ 5.56 Midlength Cold Hammer Forged Barrel 1:7 Twist

The Aero Precision 16″ 5.56 Midlength Cold Hammer Forged Barrel is a premium choice for AR-15 builders who want long-term durability and consistent accuracy under high round counts. Cold hammer forged from 4150 CMV steel, this barrel is designed to withstand heat and wear while maintaining reliable performance. The mid-length gas system helps smooth cycling and recoil impulse, making it a strong all-around configuration for training, duty use, and general-purpose rifles.

With a 1:7 twist, it stabilizes common 5.56 bullet weights—especially heavier projectiles—while M4 feed ramps support reliable feeding. Finished in manganese phosphate for corrosion resistance and a classic mil-spec look, it’s ready for builds where longevity and function come first.
