Product Description
The Shield Arms SA-15 Complete Folding Lower Receiver with Carbine Stock is a fully assembled, premium-grade AR-15 lower receiver built for shooters who demand maximum portability without sacrificing structural integrity or performance. Machined from 7075-T6 aircraft grade billet aluminum and finished in a matte black hard-coat anodize per Mil-8625 Type 3 Class 2, this lower features Shield Arms' patented built-in folding mechanism integrated directly into the receiver itself, not through an external adapter. This single-piece engineering approach adds an additional connection point for structural rigidity while saving over 0.5 lbs compared to adapter-based folding systems. Shipped fully equipped with a B5 Systems Bravo Carbine Stock, B5 Systems grip, Radian Ambidextrous Safety Selector, Enhanced Nickel Teflon Combat Trigger, and Shield Arms' proprietary H2 weight buffer, the SA-15 is ready to pair with an upper and head to the range. It accepts all standard AR-15 magazines, is compatible with most standard and aftermarket AR-15 components, is caliber marked "MULTI," and is proudly made in the USA with a lifetime warranty.
