The Lead & Steel LS556PEN-MID-16 is a 5.56mm replacement barrel built for AR-15 shooters who want a lightweight, handy setup without sacrificing reliability. Its 16-inch pencil profile keeps weight down while the mid-length gas system delivers smooth, predictable operation—a proven balance for hunting, tactical training, and general shooting. Whether you're building a new upper or refreshing an existing one, this barrel gives you the accuracy and durability Lead & Steel is known for at a straightforward price point.

The pencil profile is the real draw here: it's thinner than a standard profile, which means less mass to carry and faster handling. That matters if you're working timber, running dynamic drills, or just prefer a nimble rifle. The M4 feed ramps ensure reliable feeding across quality ammo, and the mid-length system—longer than carbine, shorter than rifle—strikes a sweet spot for velocity, recoil impulse, and component life in a 16-inch package.

Lead & Steel manufactures this barrel to the same exacting standards you'd expect from a premium domestic manufacturer. It's a straightforward upgrade or replacement that works with standard AR-15 uppers and bolt carriers. If you're looking to swap barrels, build a second upper, or just want a reliable, lightweight 5.56 barrel that won't weigh down your rifle, this is solid, no-nonsense hardware.
