Spartan Classic Key Mod MagnaSwitch Adapter
The Classic Key Mod Adapter enables fast, secure attachment of Spartan supports.
The Classic Key Mod Adapter is a lightweight and highly durable accessory that allows for quick attachment and detachment of a range of Spartan Javelin Bipods, Ascent and Sentinel Tripods, and Davros Heads to rifles equipped with genuine Key Mod accessory rails.
This convenient adapter enables seamless compatibility between your equipment and provides a secure and stable platform for your rifle in just a matter of seconds.
What Is the MagnaSwitch System?
MagnaSwitch™ is Sparta’s magnetic quick-attach technology, designed to let you mount and detach rifles, optics, bipods, tripods, or accessories in seconds.
Rather than fixed clamps or levers, the system uses rare-earth magnets as the locking force, combined with precision mechanical alignment.
You fit this small adapter to the rifle keymod slot and then any MagnaSwitch‑compatible support can snap on securely, or be removed just as fast, without tools, while maintaining alignment and zero.
It's so good for fast fitting amd removoval of a Spartan Bipod or Tripod that you'll wonder how you ever did without! Obviously you also need to buy a Spartan bipod or Tripod.

Q1: What is the Classic KeyMod Adapter for?
This adapter allows you to attach Spartan support gear — such as bipods and tripods — directly to rifles fitted with KeyMod accessory rails. It transforms the KeyMod rail into a compatible interface for Spartan’s quick-detach systems like MagnaSwitch and Disc-Lok.
Q2: What material is it made from?
The adapter is CNC-machined from strong, lightweight 7075‑T7351 aluminium, finished with hard anodising for corrosion resistance and durability.
Q3: How much does it weigh?
It weighs approximately 30 grams (1 ounce) — adding minimal weight while delivering solid mounting strength.
Q4: What Spartan gear is it compatible with?
This adapter works with a wide range of Spartan Precision Equipment, including:
-
All Javelin Bipod variants
-
Sentinel, Ascent, and Hoplite Tripods
-
SpringBok Bipods
-
Davros Heads
-
Spartan Quad Sticks and support systems that use the classic magnetic attachment
Q5: How does it attach to KeyMod rails?
It uses coned nut fittings that expand securely into the KeyMod slots. Once fitted, it provides a stable anchor point for quick-detach Spartan accessories.
Q6: What are its limitations or incompatibilities?
-
This adapter is designed only for genuine KeyMod rail systems — it will not fit M‑LOK, Picatinny, or other rail types.
-
It is a mounting interface only — bipods and other gear are not included.
-
As with all modular mounts, ensure the adapter is properly aligned and torqued to maintain reliability under recoil or field use.
-
Due to its compact size, it’s not intended to support large accessories outside of Spartan’s designed ecosystem.
