The Lead & Steel LS300-7.5 is a 300 Blackout replacement barrel built for shooters who want reliability and precision in a short, handy package. At 7.5 inches, this government-profile barrel gives you the ballistics you need for subsonic and supersonic loads while keeping your overall rifle length manageable for close-quarters work, truck guns, or suppressed builds. The M4 feed ramps ensure smooth feeding with standard magazines and bolt carriers, so you're not reinventing the wheel—just upgrading your platform.
Built to government profile specs, this barrel maintains the same diameter and taper you'd find on mil-spec uppers, so it'll drop into most AR-pattern receivers without hassle. Whether you're running a short-barreled rifle for home defense, dropping it into a pistol-caliber build, or chasing velocity and sound signatures with suppressed loads, the LS300-7.5 gives you a solid foundation to work from. The 300 Blackout round thrives at shorter barrel lengths, so you're not leaving performance on the table.
Lead & Steel barrels are known for holding tight tolerances and consistent quality without the premium markup. If you're building or upgrading an AR and want a no-nonsense barrel that shoots, this is worth your consideration. Pair it with the right bolt carrier and upper receiver, and you've got a capable rig.

Yes, the government profile and M4 feed ramps are standard AR-pattern specs, so it's compatible with mil-spec uppers and bolt carriers.
300 Blackout is excellent for suppressed setups, especially with subsonic ammunition. The 7.5-inch barrel supports both subsonic and supersonic loads effectively.
The LS300-7.5 is chambered in 300 Blackout, a powerful cartridge that performs well in short barrels and pairs well with suppressors.
A barrel vice, upper receiver vise block, and armorers wrench are the standard tools needed for AR barrel installation. Professional installation is also an option if you prefer.
