Daniel Defense S2W Barrel Assembly 5.56 18 Barrel for AR-15

Overview

Daniel Defense S2W Barrel Assembly Features The Daniel Defense S2W Barrel Assembly is built on an 18-inch heavy barrel profile with a 1:7 twist rate optimized for stabilizing heavier .223 Rem/5.56 NATO projectiles at extended range making it a natural fit for precision shooting applications where bullet stability and downrange accuracy are the primary objectives. The rifle-length gas system provides a longer dwell time compared to mid-length or carbine configurations reducing felt recoil impulse and producing a smoother and more consistent cycling rhythm that benefits both accuracy and long-term component wear. For precision rifle builders and long-range competitive shooters who want a Daniel Defense quality barrel assembly with a proven gas system configuration optimized for 18-inch performance the S2W Barrel Assembly delivers exactly that. The S2W Barrel Assembly heavy profile adds mass compared to a government or SOCOM contour improving heat dissipation during extended range sessions and sustained fire drills while contributing to a more stable harmonic during the shot cycle. The matte black finish provides a non-reflective field-ready appearance and a degree of corrosion resistance suited for varying environmental conditions. For AR-15 builders who want a precision-oriented heavy profile barrel assembly from one of the most trusted names in the industry with a matte finish ready to drop into a build the Daniel Defense S2W Barrel Assembly is available at GrabAGun.
