The Lead & Steel JAG-18 is a match-grade 5.56mm replacement barrel built for shooters who want precision on a mid-length platform. At 18 inches, this barrel splits the difference between maneuverability and velocity, making it a solid choice for AR-15 builds aimed at accuracy-focused shooting—whether that's competition, training, or long-range hunting applications where a shorter, handy profile doesn't sacrifice ballistic performance. Match-grade barrels hold tighter tolerances than standard mil-spec alternatives, and that consistency matters when you're chasing tight groups.
This is a barrel, not a complete upper or rifle, so you're looking at a component swap for an existing AR-15 platform. If you're re-barreling your current rifle or building a precision-focused upper from parts, a match-grade tube gives you a real foundation for accuracy. The 5.56mm NATO chambering keeps you aligned with standard ammunition and platform compatibility—no special feeding or extraction concerns.
Lead & Steel focuses on match-grade components, so this barrel reflects that attention to detail. Black finish handles corrosion resistance and blends with most upper receiver builds. Installation requires proper tools and knowledge (or a qualified gunsmith), but the payoff is a barrel that'll support your accuracy work for years.

This is a 5.56mm match-grade barrel designed for AR-15 builds. Barrel installation requires proper headspacing tools and knowledge; we recommend a qualified gunsmith if you're not experienced with the process.
An 18-inch barrel offers a practical middle ground: it's handy for movement and shooting in tight spaces, but long enough to extract good velocity from 5.56mm rounds. It's a common choice for precision shooting, training, and hunting applications where you want accuracy without excessive length.
Match-grade barrels are held to tighter manufacturing tolerances than standard mil-spec barrels, resulting in more consistent bore and chamber dimensions. That consistency translates to better accuracy potential and tighter group potential downrange.
This is a barrel only. You'll need to source and install a muzzle brake, flash hider, or suppressor adapter separately, depending on your build and local regulations.
