Heavy-duty side-folding stock adapter for AR-platform rifles. Constructed from 4140 steel with full-length locking lug. Configurable for left or right folding. Includes buffer tube adapter. Adds 2.5 inches open, 0.75 inches folded.
The Midwest Industries Side Folder represents a practical solution for shooters who need a compact, reliable stock adapter without sacrificing strength or functionality.
This side-folding mechanism is machined from 4140 steel—a material chosen for its durability and resistance to wear. The full-length locking lug provides maximum strength, while the solid positive lock-up in both open and folded positions ensures your stock stays exactly where you place it. The steel clamp features large surface engagement for secure mounting to your Picatinny rail.
The modular design accommodates different stock attachments, and you can configure the folder to fold either left or right depending on your preference and shooting style. The included buffer tube adapter allows you to attach standard Mil-Spec buffer tubes, giving you flexibility in stock selection.
This is a no-nonsense accessory built for function and longevity.
