ARES M4 Foldable Buffer Tube w/ Lock Adapter for VZ58 AEG, Black

Standard M4 buffer tubes don't work on a VZ58 — that's a bullpup, and its stock well isn't the right profile for an SR-25 or A4 tube. This adapter solves the problem by giving your VZ58 a proper buffer tube so you can mount a standard 6-position stock for stability and fit adjustment.

How it works. The buffer tube folds via a standard lever on the bottom — pull it back and the tube rotates parallel to the receiver, cutting down overall length for CQB lanes, vehicle transport, or compact storage. Deploy it and the tube locks into the 6-position telescoping profile. Any M4 or CAR-style stock slides on and adjusts freely. The buffer tube is aluminum, so it's stiff and will hold up to repeated folding.

Compatibility. This is an adapter for the VZ58 AEG. It replaces the rear buffer tube area on that rifle specifically — it won't drop onto an M4, AK, or any other platform. If you're running a VZ58 and want a real adjustable stock instead of a polymer comb attachment, this is the interface that makes it happen.

What's in the box. The buffer tube and lock adapter. No stock is included, and you'll need one that fits M4-profile 6-position tubes. The tube is black with a standard anodized finish.
