The Primary Arms SLx Top Cap Reflex Mount (Primary Arms part no. 910115) is built specifically for use with 34mm SLx scope mounts, letting you mount a 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 paired with the 34mm SLx 1.5-inch mount, it places the base of your red dot at 2.04 inches, letting you simply raise your head to use the sight rather than hunting for a separate cheek weld. The footprint is compatible with the Primary Arms Classic Series 24mm Mini Reflex Sight or any other Holosun 507c-footprint optic, and it’s machined from 6061 aluminum to hold zero over time, backed by the Primary Arms Lifetime Warranty.
