A3 Industries HDA3 Hybrid Polymer Folding Brace (PSA JAKL)

The A3 Industries HDA3 is the JAKL-specific version of A3's hybrid-polymer folding brace, built with Haga Defense. It bolts to the PSA JAKL's rear interface directly rather than stacking on a 1913 adapter, which keeps the lockup tight. The hinge is 17-4 stainless steel, and the body is a 30% glass-filled polymer, the same construction A3 uses on its Kuna and universal HDA3 braces.

The brace folds left, clearing the ejection port and a mounted optic when stowed, and the rifle stays operable folded. It is machined for the JAKL rear, so there is no 1913 adapter to stack, but the buffer ring, JAKL threaded adapter, and screw are not in the box: reuse the hardware from your factory endcap or add A3's JAKL-15 buffer kit. A3 offers it in Black, ODG, and FDE, and the same HDA3 body is also sold as a rifle-stock variant for SBR-configured or rifle-length JAKL builds.

This is the brace answer for a pistol-configured JAKL that wants a rigid steel-hinge folder without the slop of a universal 1913 stack. It is also sold direct by Haga Defense at $350.
