Nuprol / Vorsk | VMP 20mm Stock Adapter (4-Slot)

Want to run a RIS stock on your VMP or another GBB M4-spec receiver? This OEM Vorsk adapter replaces the buffer tube interface with a four-slot 20mm RIS rail at the rear. No sling points, just a solid mount for RIS stocks.

It is the original VAC-11-08 part from the Vorsk Modular Platform accessory range, so fitment matches the factory parts.

Fits: Vorsk / Nuprol VMP-1 and VMP-2, and other GBB M4/AR-spec receivers with a buffer tube receptacle

In the box: 1x 4-slot 20mm stock adapter, 1x circular plate, 1x mounting bolt
