The Seekins SP10M .308 Win 16" FDE Complete Upper offers a compact, versatile configuration for shooters looking to build or upgrade a semi‑auto AR‑10–pattern rifle with a powerful and widely used cartridge. Its 16" barrel and Flat Dark Earth finish combine compact handling and a tactical, low‑visibility aesthetic suitable for field, duty, or range use. Built as a complete upper assembly — including receiver, barrel, handguard, and gas system — it’s ready to install on a compatible lower without additional fitting required. The free‑float M‑LOK handguard provides flexibility for accessories such as optics, lights, or bipods, while the threaded barrel supports muzzle devices or suppressors. This configuration strikes a balance between mobility and capability, making it a strong choice for shooters who want .308 Win performance in a shorter, modular platform.
