Description
Ares M4 Fixed Buffer Tube (with Buffer Tube Lock Adapter for VZ58)
This Ares part combines a fixed M4-style buffer tube with a lock adapter, made to let you fit an M4-type stock to the Ares VZ58. A retailer listing for this Ares part (code BT-008) describes it as a stock adapter with a stock tube for the Ares VZ58, giving the rifle an M4-style stock for added stability.
The VZ58 is a classic Czech design and Ares produces some of the best-known airsoft replicas of it. Switching to an M4-pattern buffer tube opens up a huge choice of adjustable stocks, so you can set the length of pull to suit your build and your kit. This is the fixed version; a foldable version is also listed.
Why fit it
The standard VZ58 stock limits your options. With an M4 buffer tube fitted, you can use almost any M4-style stock, from simple six-position designs to modern adjustable stocks, and set the length for body armour, a plate carrier or a smaller frame.
A fixed tube gives a solid, rigid connection between stock and receiver, without the hinge of a folding design, which some players prefer for a steady cheek weld.
Fitting
Fitting involves removing the existing stock from the rear of the receiver. If your rifle stores its battery in the stock area, plan where the battery and wiring will go before you start, and check the space available inside your chosen M4 stock or tube. If you are not confident, an airsoft technician can fit it for you.

Compatibility
Listed for the Ares VZ58. VZ58 replicas from other makers may differ at the rear of the receiver, so check your rifle’s make and compare with the product images before ordering. An M4 stock is not listed as included; most M4-pattern stocks are made for this type of tube, but check your chosen stock suits it.
Care and maintenance
After fitting, check that the tube is tight and does not rotate, and recheck the fixings after the first game day. Wipe off mud and grit and store the rifle dry.
If the battery lives in or near the tube, check the wiring is not pinched each time you fit or remove the stock.
Who is it for?
Ares VZ58 owners who want a solid, fixed mount for an adjustable M4-style stock for better fit and comfort with their kit.
Please note: An M4 stock is not listed as included. If you are not confident fitting it, please have it fitted by a technician.
