Designed specifically for use with the 34mm SLx scope mounts, this top-cap reflex mount lets you 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 with the 34mm SLx 1.5" mounts, it places the base of your red dot sight at 2.04", allowing you to simply raise your head to use the sight. This red dot mount features a footprint compatible with the Primary Arms Classic Series 24mm Mini Reflex Sight or any other Holosun 507c footprint optic. Machined from 6061 aluminum, this red dot mount is built to last without losing zero and comes with the Primary Arms Lifetime Warranty.
