Description
Specifically engineered for use with 34mm SLx scope mounts, the SLx Top Cap Reflex Mount allows you to securely mount a 24mm reflex sight directly above your primary optic. Placing your red dot at the 12 o’clock position, this setup enables fast, intuitive transitions from magnified targets to close-quarters shots — ideal for Aussie shooters running tight drills or multi-distance stages.
When paired with 1.5” SLx 34mm mounts, the reflex optic is positioned at a precise 2.04” centreline height, allowing a simple head lift for rapid dot acquisition. The mount is designed for the Primary Arms Classic Series 24mm Mini Reflex Sight and any optic using the Holosun 507C footprint. Precision-machined from 6061 aluminium and finished in black hardcoat anodising, it provides lasting strength, repeatable zero retention, and is backed by the Primary Arms Lifetime Warranty — a serious upgrade for any professional setup.

Another key advantage of the piggyback-style top mount is its true ambidextrous usability — giving you a clear view of your red dot regardless of which shoulder you’re shooting from. Compared to traditional side-offset mounts, the 12 o’clock position provides greater visibility and a more consistent head-up shooting posture. However you choose to configure your backup or transitional sight, you can rely on Primary Arms SLx mounting solutions for durability, precision, and flexibility in any scenario.
