Lead & Steel LS556PEN-MID-14.5 5.56mm 14.5″ Pencil Profile AR-15 Barrel with M4 Feed Ramps

Upgrade your AR-15 build with the Lead & Steel LS556PEN-MID-14.5, a precision-machined 14.5-inch pencil profile barrel chambered in 5.56mm NATO. Crafted from 4150 Chrome Moly Vanadium Steel and finished in a durable QPQ Black Nitride coating, this barrel delivers outstanding corrosion resistance, enhanced surface hardness, and long-term reliability under demanding conditions.

The pencil profile keeps your build lightweight and maneuverable without sacrificing strength, making it an excellent choice for tactical applications, competition shooting, and custom AR-15 builds. M4 feed ramps ensure smooth, reliable feeding across a wide range of ammunition types. The mid-length gas system offers a balanced dwell time for softer recoil and consistent cycling.

Whether you’re completing a custom build or upgrading an existing rifle, the Lead & Steel LS556PEN-MID-14.5 offers professional-grade quality at a competitive price point. Please note that a 14.5-inch barrel requires a permanently attached muzzle device to reach the federally required 16-inch overall barrel length, or must be configured as an NFA-regulated Short Barreled Rifle (SBR) in compliance with all applicable federal, state, and local laws.
