Primary Arms Optics SLx Offset Reflex Mount Keeper - 32.5 Degree Offset

The Primary Arms SLx Offset Reflex Mount Keeper (SLx R.O.K.) is an upgrade accessory designed for Primary Arms SLx one-piece cantilever scope mounts, letting the shooter attach a mini reflex sight directly to the mount's integrated keeper. It uses a 32.5-degree offset angle so a backup red dot sits ready for fast, intuitive transitions without the need for a separate mount or plate stack.

Built to fit SLx 30mm and 34mm cantilever scope mounts, this keeper gives long-gun shooters a co-witnessed reflex option right on top of their existing SLx scope ring. The offset geometry keeps the reflex optic out of the primary scope's sight picture until the shooter rotates the rifle to engage it, making it well suited for close-quarters follow-up shots after dialing in at distance.

The SLx Offset Reflex Mount Keeper installs directly to the keeper area on a compatible SLx mount and is compatible with standard mini reflex sights using the GLOCK MOS pattern adapter plate footprint. Once installed, it provides a versatile backup optic setup on a single, streamlined platform.

Part of the Primary Arms SLx line, this offset keeper ships ready to install and reflects Primary Arms' focus on affordable, dependable optic-mounting hardware.
