The One Horse 16-Inch Mid-Length SOCOM Barrel (One Horse part no. OHBR03) is chambered in 5.56 NATO and cut with a SOCOM-profile contour, a heavier, government-style taper that adds durability and heat capacity over a pencil-thin barrel while staying lighter than a full bull profile. The mid-length gas system gives the AR-15 platform a longer dwell time and gentler cycling than a carbine-length setup, which typically means less felt recoil and reduced wear on the bolt carrier group over the life of the rifle. It is a solid choice for a general-purpose AR-15 build meant to run reliably across a wide range of ammunition.
