A stamped metal, side-folding stock of triangular shape designed for a specific rifle platform offers a compact profile for easier maneuverability and storage, compared to traditional fixed stocks. This design often features a locking mechanism to secure it in both the folded and extended positions.
The compactness provided by such a stock is particularly advantageous for close-quarters combat and transport. When folded, the overall length of the firearm is significantly reduced, allowing for easier movement in confined spaces and discreet carry. When extended, it provides a stable platform for aiming and firing. This type of stock emerged as a practical solution for airborne troops, special forces, and other operators requiring a balance between portability and weapon handling.
