The VMP 20mm Stock Adapter (3-Slot + QD Stud) converts a standard GBB M4-spec buffer tube receptacle into a rear-mounted 20mm RIS platform. Once installed, the adapter provides a three-slot rail section suitable for attaching RIS-based stock systems, opening up modern and unconventional rear-end configurations beyond traditional buffer-tube solutions.

To support versatile sling setups, the adapter includes QD sling points on both sides, giving players the freedom to balance their sling placement for comfort, transitions or one-point carry styles. Its lightweight yet durable construction ensures a secure interface for both stocks and slings, even during fast-paced CQB movement.

Compatible across the VMP series as well as other GBB M4-spec platforms, this adapter is a flexible upgrade for builders exploring new stock geometries and custom layouts.
