Shield Arms SA-15 Complete Folding Lower Receiver, Multi

Description

The Shield Arms SA-15 is a complete billet lower receiver for AR-15 style builds featuring a built-in folding mechanism designed for compact storage and transport; this is explicitly a built-in folding system and not an adapter. Machined from 7075-T6 aircraft-grade billet aluminum and finished in matte black hard-coat anodize, the SA-15 ships with a B5 Systems Bravo rifle stock and is marked “MULTI” for caliber flexibility. The lower accepts standard AR-15 magazines and is compatible with most common AR-15 components and aftermarket parts.
