ZENITH ZF-5 A3 4-Position Retractable Stock - Premium Tactical Upgrade

The Zenith ZF-5 A3 4-position retractable stock brings proven tactical ergonomics to your full-size MP5 platform. Built on genuine A3 design specifications, this stock gives you the adjustability serious shooters need—whether you're running drills at the range, working through a home-defense scenario, or setting up for precision shooting. The four-position locking system locks solid at each setting, so your stock stays where you put it under recoil and movement.

Construction matters with a stock that takes real use. The steel-reinforced polymer shoulder pad is built to handle serious shooters and serious conditions. This isn't a flimsy upgrade; it's engineered to deliver the stability and repeatability that makes a difference when your setup matters.

If you run a full-size MP5 platform—whether it's a ZF-5, SP5, MP5-SD, or another standard MP5 model—this stock is a direct fit. It's the kind of foundational upgrade that transforms how your rifle handles, especially if you've been running an older or less adjustable setup.

Retractable stocks on MP5s strike a balance: they compress for vehicle work, tight spaces, or shorter shooters, then extend for a proper cheekweld and full sight picture when you need it. The A3 platform delivers that flexibility without sacrificing the rugged reliability MP5 users expect.
