Product Description
The 3KeyzTactical 10.5″ .300 Blackout AR‑15 pistol upper is built for shooters who want compact performance without sacrificing durability or modularity. Designed around a 10.5‑inch barrel chambered in .300 Blackout, this setup is optimized for short‑barrel efficiency, making it ideal for close‑range applications, training, and tactical builds.
This upper features a pistol‑length gas system for reliable cycling in a compact platform and a 1:7 twist rate, allowing effective stabilization of a wide range of bullet weights, including heavier subsonic loads. A fixed front sight base (FSB) provides a robust, proven sighting solution while maintaining a classic tactical profile.
The carbine‑length quad‑rail handguard offers solid heat resistance and multiple mounting points for accessories such as optics, lights, grips, and lasers. Built for strength and versatility, the quad‑rail design ensures secure attachment and consistent performance under use.
Whether you’re assembling a compact AR‑15 pistol build or upgrading an existing platform, this 3KeyzTactical upper delivers reliability, adaptability, and a no‑nonsense tactical aesthetic — ready to be configured to your mission needs.
