Description
The Lead & Steel LS556PEN-MID-14.5 is a match-grade AR-15 barrel chambered in 5.56 NATO and cut from a 14.5″ pencil-profile blank with a fast 1:7 rifling twist. It is designed for AR-platform builds where a compact, lightweight barrel is needed without giving up the accuracy and reliability expected from a duty-grade component.
The blank is turned from 4150 Chrome Moly Vanadium Steel, a high-strength alloy widely chosen for service-rifle and match barrels because of its excellent pressure handling and long service life under sustained fire. It is then treated with a QPQ Black Nitride finish, a salt-bath process that hardens the surface, lowers friction, and provides outstanding corrosion and wear resistance without the dimensional buildup of a sprayed-on coating.
A mid-length gas system keeps reciprocating mass balanced and the recoil impulse soft, while M4 feed ramps are machined into the extension to ensure reliable feeding from the magazine into the chamber across a wide range of ammunition. The pencil profile keeps the front of the rifle light and quick to swing, making this barrel a strong choice for a carbine build, a compact rifle project, or a replacement barrel on an existing platform.
Suitable for custom builds, replacement upgrades, and short-barreled rifle (SBR) projects subject to applicable NFA regulations, this Lead & Steel match-grade pencil-profile barrel delivers serious accuracy potential in a lightweight, easy-handling package for the modern AR-15.
