5KU AB-8 Folding Stock

Looking for a lightweight yet durable folding stock that fits RIS (1913) stock mounts and folds to either side for easy transport or compact use? Need a QD sling mount for quick tactical attachment? The 5KU AB-8 stock combines stability, strength, and practicality in a clean, minimalist design. The aluminum skeleton frame keeps the stock lightweight and ergonomic, while the steel mounting base ensures a solid connection to any 1913 rail.

Installation is simple and tool-friendly. The AB-8 is fully compatible with 5KU RIS adapters for M4, MP5, or AK rifles, opening new options for custom builds and tactical upgrades.
