The Shield Arms SA-15 Complete Folding Lower Receiver with B5 Bravo Stock is a semi-automatic lower receiver assembly chambered in 223 Remington/5.56 NATO, purpose-built for operators and shooters who prioritize modularity and compact storage. This complete lower receiver arrives fully assembled with Shield Arms' proprietary H2 buffer weight and B5 Systems Bravo stock, eliminating the need for secondary component sourcing and reducing assembly complexity on the firing range or in the field.
The folding stock design significantly reduces overall profile when collapsed, essential for transport in confined spaces, vehicle mounting, or dynamic entry scenarios where extended length becomes a liability. The anodized black finish provides corrosion resistance in field conditions while maintaining a clean, professional aesthetic. The H2 proprietary buffer weight system is engineered to manage recoil impulse across the 223 Remington and 5.56 NATO spectrum, maintaining reliability and shootability across both commercial and military ammunition variants. The B5 Systems Bravo stock is recognized in the tactical community for ergonomics and adjustability, offering shooters the ability to dial in length of pull and comb height for precision and comfort during extended range sessions or duty applications.
This complete lower receiver serves law enforcement, military personnel, competitive shooters, and civilian tactical enthusiasts who demand a platform that balances functionality with practical storage constraints. The ready-to-use configuration accelerates system deployment and reduces integration variables, making it ideal for operators who value reliability and immediate mission readiness. As a lower receiver, this component retains the legal designation as a firearm under federal classification and is subject to applicable FFL requirements and state regulations.
At 3.94 lbs and designed within compact dimensions, the SA-15 complete folding lower offers a substantial foundation for mid-range to precision build-outs while maintaining the portability that separates it from full-size rifle platforms.
