Shield Arms offers a folding option for AR-15s with its SA-15 FLR lower receivers

The Shield Arms SA-15 built on the patent-pending FLR folding lower receiver is shipping now in stripped lower and complete pistol configurations. The FLR is billed as “…the world’s first folding AR-15 lower receiver – no adapter required.”

The Folding Lower Receiver (FLR) features a folding stock mechanism machined and built directly into the receiver, allowing the stock or pistol brace to fold without the need of an aftermarket folding stock adapter. The FLR is one of several innovative products we expect to see from Shield Arms, which was originally known for magazine accessories (like their extensive magazine extension line for all types of pistol magazines).
