Description

The Strike Industries FSA Dual Folder Stock Edition is a preassembled folding stock system for compatible platforms with a rear-facing 1913 Picatinny interface. Its dual-folding hinge can fold to either the left or right without reconfiguring the assembly, giving builders more flexibility around controls, ejection-port clearance, storage, and transport.

The stock assembly combines a steel hinge with a 6061-T6 aluminum base, adapter, and strut. A positive folded-position lock, rubber anti-slip buttpad, ambidextrous QD sling sockets, and included tension-adjustment pads support practical setup and repeatable deployment.

Key Features

  • Preassembled FSA Stock Edition
  • Folds left or right without reversing the hinge
  • Direct attachment to compatible rear-facing 1913 Picatinny interfaces
  • Two built-in locking lugs
  • Positive lock in the folded position
  • Quick deployment by lifting and pulling the hinge bar
  • 3-degree downward cant to help reduce right-side ejection-port interference
  • Ambidextrous QD sling mounting points
