Seekins SIC Long Action AICS Magwell 11700471F

The Seekins SIC Long Action AICS Magwell is a caliber-specific magazine well insert designed exclusively for the Seekins SIC modular rifle system, enabling the platform to accept long-action AICS-pattern magazines for cartridges including .300 Winchester Magnum and .300 PRC. Part of the SIC's complete Caliber Change Kit alongside a barrel, bolt head, and magazine, the magwell swaps via simple takedown pins without tools, maintaining the SIC's zero-repeatability and system integrity across caliber configurations. Machined from high-strength aluminum and finished in matte black, the magwell features an ambidextrous magazine release and oversized well for fast, reliable reloads in field and tactical environments.
