Seekins SIC .338 Magwell 11700473F

The Seekins SIC .338 Magwell is a caliber-specific magazine well insert designed exclusively for the Seekins SIC modular rifle system, enabling the platform to accept .338 class magazines for cartridges including .338 Lapua Magnum and .338 Norma Magnum. 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.
