As part of the PLx line, this reflex mount meets the exacting demands of professional use, offering impeccable craftsmanship and advanced features.

Designed specifically for use with the 30mm PLx scope mounts, this top-cap reflex mount allows you to easily mount your Primary Arms 24mm mini reflex sight at the 12 O’clock position above your scope for fast transitions from medium range to close quarters. When used on the 30mm PLx 1.5” mounts, it will place the base of your red dot sight at the 2.04” height allowing you to simply raise your head to use the sight. This red dot mount features a footprint for use with the Primary Arms Classic Series 24mm Mini Reflex Sight or any other RMR footprint optic. Machined from 7075 aluminum and made in America, this red dot mount is built to last without losing zero and comes with the Primary Arms Lifetime Warranty.

  • 7075 Aluminum construction
  • Black hardcoat anodized finish
  • For use with 1.5” PLx 30mm scope mounts
  • 2.04” height for the red dot sight at the base
  • RMR style footprint
  • Made in America
  • 16-18 in. lb. Recommended torque specs
  • Primary Arms Lifetime Warranty

Another benefit of the piggyback style of offset red dot mount is the ability to still use your red dot no matter which side you are shouldering your rifle and in general gives you more ways to see your dot than compared to the more common style of offsetting your red dot to one side. Whichever way you decide to mount your backup or transitional red dot sight, you can’t go wrong with a Primary Arms PLx mounting solution.

Quite nice


It works good, mounted easily. Put the PA classic 24mm red dot on it and it is solid.
