The 5KU AB-8 stock is a foldable, versatile, and functional solution, ideal for those seeking lightness (only 260g) and practicality without compromising strength. The skeletonized design reduces weight to a minimum and improves the replica's handling.

The construction is hybrid and high-quality: the hinge and mounting block are made of robust steel for maximum durability, while the stock body is made of lightweight aluminum.

This stock uses the modern mounting standard on RIS Picatinny (1913) rail. This makes it natively compatible with replicas such as the SIG MCX/MPX, but also universally adaptable to M4, AK, or MP5 platforms equipped with the appropriate 5KU adapters (sold separately).

Its strength is the ambidextrous hinge: the design allows the user to configure the stock to fold on either the right or left side, depending on their preferences or the presence of side-mounted optics. It includes a QD sling mount and the provision for an optional cheek pad.

Main Advantages

  • Universal RIS 1913 Mount: Mounts on Picatinny rails (SIG MCX, 5KU adapters).
  • Ambidextrous Folding: Configurable to fold to the right or left.
  • Premium Hybrid Construction: Steel hinge and base, Aluminum body.
  • Skeleton Design: Extremely lightweight (260g) and aggressive look.
  • Integrated QD Attachment: For quick sling mounting.
