The Seekins SIC rifle has been designed and crafted specifically for U.S. Special Operations. Built to withstand extreme environments while letting the operator rapidly select and swap calibers to meet mission criteria the SIC is a purpose-driven modular system — not a chassis retrofitted to accept a barreled action. The SIC receiver removable grip & trigger assembly and dedicated caliber-specific magazine wells come together with pinpoint precision swapping tools and screws for simple take-down pins. The only service tool required is a T25 which is stored in the butt pad. The SIC is able to run a variety of calibers from long action to short action allowing maximum performance and modularity out of a single system.
