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 the adapter to the rifle (super easy), 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 easya nd fast that you'll wonder how you ever did without it!

Q1: What is the Classic Arca Adapter for?
The adapter lets you mount Spartan supports (bipods, heads, tripods) to an Arca‑Swiss style rail interface. It transforms your gear into a stable modular platform while retaining quick‑detach functionality.
Q2: What material is it made from?
It is machined from high‑grade aluminium (7075 or similar), with a durable anodised finish to resist corrosion, wear and field use.
Q3: How much weight does it add?
Very little — designed to be lightweight so it doesn’t significantly affect balance or handling.
Q4: What Spartan gear is it compatible with?
Compatible with the Spartan line: Javelin bipods, Sentinel tripods, Davros heads, and any support that uses the classic Spartan mounting interface.
Q5: How does it attach to Arca rails?
It clamps into the Arca‑Swiss channel using precision surfaces and screw. The interface aligns and locks in place so Spartan supports can then quick attach and detach easily.
Q6: What are its limitations?
-
Only works with genuine Arca‑Swiss style rails, not with other rail types
-
It is a mounting adapter only — does not include the support (bipod, tripod, etc.)
-
Correct alignment, torque, and installation are essential for repeatability and zero retention
-
It may not support excessive lateral loads if improperly mounted — use within rated limits of Spartan supports
