5KU Minimalist Folding Stock for MCX / MPX 1913 Picatinny Rail

At Bullseye Country Sport, we've found 1913 Picatinny stock systems have become increasingly popular thanks to their versatility and ease of installation. A folding stock is an excellent upgrade for players looking to reduce the overall length of their rifle for transport, storage, or close-quarters use without sacrificing stability when deployed.

The 5KU Minimalist Folding Stock is a lightweight stock designed for rifles and SMGs equipped with a 1913 Picatinny rear stock interface. Constructed from CNC aluminium with steel components in key stress areas, it combines durability with a low-profile design. The side-folding mechanism allows the stock to be folded when not in use, while the minimalist skeletonised construction helps keep overall weight to a minimum.

Designed around the MCX and MPX platform, the stock also fits other airsoft rifles and SMGs equipped with a 1913 Picatinny stock mounting point. A rubber butt pad improves shoulder grip, while integrated QD sling points provide convenient sling attachment options.

Compatibility Note: Designed for MCX, MPX and other platforms equipped with a 1913 Picatinny stock interface. Not compatible with standard M4 buffer tube receivers without a suitable 1913 stock adapter.
