Olight Osight R Low Height Picatinny Riser Mount 1.21" - ORL-121

Olight Osight R ORL 1.21" Low Profile Picatinny Riser Mount 1.21 Inch 6978095650469

Product Description

The Olight Osight R ORL-121 Low-Profile Picatinny Riser Mount (ORL-121) is a precision-engineered optical riser designed to securely mount red dot optics sharing the industry-standard Aimpoint® Micro T-1/T-2 footprint—including the Olight Osight R—onto MIL-STD-1911 Picatinny rails. Positioning the optical centerline at 1.21 inches above the top rail, the ORL-121 provides a compact, low-profile cheek weld optimized for shotguns, pistol caliber carbines, AK-platform receivers, and weapons requiring an ultra-low optic plane.

Constructed from lightweight, aircraft-grade 6061 aluminum with a Type III hard-anodized matte black finish, the ORL-121 combines extreme durability with minimal added height and weight. Engineered to endure harsh operational environments, the housing is rated for up to 1,000G of impact recoil resistance while weighing a mere 1.38 ounces.

Equipped with a heavy-duty steel clamp and a robust rail-locking screw, the Olight ORL-121 secures tightly across receiver rail slots for rock-solid zero retention. Ideal for hunting, tactical staging, and low-profile long gun setups, this compact mount delivers broad compatibility across modern micro red dot optics with minimal footprint obstruction.

*Armorer Bench Notes & Real-World Staging Guidance:*

Fitment Matrix: Direct fitment for all standard MIL-STD-1911 Picatinny receiver rails. Compatible with all micro red dot optics featuring the Aimpoint® Micro T-1/T-2 footprint (e.g., Olight Osight R, Aimpoint Micro T-1/T-2/H-1/H-2, Holosun 403/503/515, Sig Sauer Romeo4/Romeo5, Vortex Crossfire/SPARC AR) to achieve a 1.21" optical centerline height.

1. Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
2. Clean and inspect the receiver Picatinny rail section and the underside clamping surface of the ORL-121 mount.
3. Place the ORL-121 onto the desired rail slot, pushing it forward toward the muzzle to seat the cross-bolt firmly against the rail recoil lug.
4. Secure the optic to the top mounting surface using the included M3 screws (or optic-specific hardware), applying medium-strength threadlocker (Blue 242/243) and torquing to 15 in-lbs. Tighten the rail-clamp screw using the included T25 Torx wrench to 25–30 in-lbs for secure retention.
