Primos 65906 Heavy Optics Adapter - Gray Magnetic Fit for Apex Spartan Head
- Material:
- Magnet
The Primos Heavy Optics Adapter is a magnetic-attachment solution that transforms your Apex Spartan head into a versatile mounting platform for cameras, optics, and other gear. If you're running trail cameras, spotting scopes, rangefinders, or secondary optics on a shooting stick or tripod head, this adapter bridges the gap between your gear's threading and the Apex's quick-change magnetic system. The magnetic fit means zero fussing with traditional clamps—just align and attach in seconds.
Security matters when you're behind glass or glass-adjacent equipment. This adapter includes an adjustable lever system that locks your optic or camera down after you've positioned it magnetically, so there's no creep or shift once you're dialed in. The design is lightweight and built to handle field use without adding unnecessary weight to your kit.
What you get: the adapter itself in gray, a standard 1/4"-20 camera/optic screw, a 3/8"-16 bushing, and a polymer mounting plate. This combo covers most common threaded mounting points on aftermarket optics and cameras, but confirm your specific gear's threading before purchase.
