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 Holosun 507c 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.
