Sco Sco15 Billet Lower Receiver Blk

The SilencerCo SCO15 Billet Lower Receiver Blk is a precision-engineered component built for AR-15 platform rifles requiring exceptional build quality and reliability. Designed by SilencerCo, a manufacturer known for suppressor and firearm component innovation, this billet lower receiver serves as the registered firearm component for custom AR-15 builds in law enforcement, military, and civilian tactical applications. The black anodized finish delivers both aesthetics and corrosion resistance suitable for demanding operational environments and long-term storage.

Machined from solid aluminum billet stock rather than forged material, this lower receiver exhibits superior dimensional consistency and structural integrity across critical areas including the trigger group pocket, magazine well, and buffer tube interface. The billet manufacturing process allows tighter tolerances during production, reducing wear patterns in the hammer and trigger pin holes—a significant advantage in high-round-count service rifles. Weighing 0.94 lbs and measuring 6 x 3.3 x 10.3 inches, the receiver accommodates mil-spec upper receivers and standard fire control groups without modification, ensuring drop-in compatibility with proven AR-15 platform components.

Armorers, tactical shooters, and builders selecting the SilencerCo SCO15 Billet Lower Receiver Blk gain a foundation component engineered for precision and longevity in suppressed or unsuppressed rifle configurations. Installation pairs with any mil-spec upper receiver assembly, standard lower parts kit, and buffer tube system—making this receiver suitable for 5.56 NATO, .223 Remington, and other AR-15 caliber conversions. Whether building a duty rifle, precision platform, or feature-rich civilian tactical system, this billet lower receiver provides the dimensional accuracy and material quality that separates quality builds from compromised assemblies.
