The Seekins SP10M 16" Black Complete Upper offers a compact and robust AR‑10 pattern setup, chambered in .308 Winchester for reliable power and versatility. With a 16" 416‑stainless barrel featuring 5R rifling and a free‑float 15" SP3R M‑LOK handguard, it delivers a balance of maneuverability and precision — ideal for tactical, duty, hunting, or range use. The threaded muzzle and adjustable gas block provide flexibility for muzzle devices or suppressors, while the rigid upper‑receiver assembly gives a stable, no‑flex platform for consistent accuracy even under repeated fire. At roughly 7.2 pounds for the upper assembly alone, this configuration remains manageable and easy to handle, making it a strong choice for shooters who want a .308‑caliber platform that’s both compact and uncompromising in build quality.
