5KU 1913 Stock Adapter For VFC Airsoft GBB MP5 Black

5KU 1913 Stock Adapter For VFC Airsoft GBB MP5 Black

Give your VFC MP5 GBB a more modern and versatile stock setup with the 5KU 1913 Stock Adapter.

Designed specifically for compatible VFC / Umarex MP5 Gas Blowback airsoft replicas, this compact adapter replaces the original rear stock mounting arrangement with an M1913 / 20mm Picatinny rail interface.

The addition of a 1913 rail opens up a wide selection of aftermarket stock options, including compatible folding and rail-mounted stock systems.

This makes the 5KU-407 particularly useful for custom MP5 builds where a more compact folding configuration or modern stock design is preferred.

Constructed from CNC-machined aluminium alloy, the adapter offers an excellent balance between strength and low weight. Its black anodised finish gives the unit a clean appearance that blends neatly with the MP5 receiver while also helping protect the aluminium surface during regular use.

An integrated QD sling mounting point provides a convenient location for attaching a compatible push-button sling swivel, helping keep the rear of the replica clean and uncluttered.

The 5KU 1913 Stock Adapter is a great choice for anyone building a customised VFC MP5 GBB, providing a strong and compact foundation for modern M1913-mounted folding stocks without compromising the classic MP5 platform.
