Leapers UTG 3 Slot Compact Riser Mount 83 Medium Compact Height Picatinny Black MNT RS08S3 UPC 4712274526501

Product Description

The Leapers UTG 3-Slot Compact Picatinny Riser Mount (MNT-RS08S3) in Black is a rugged, medium-profile optic elevation platform designed to elevate micro red dot sights, reflex sights, and compact tactical optics on AR-15 and long gun platforms. Featuring an 0.83-inch riser height and a compact 3-slot Picatinny rail length (1.6 inches), this riser raises low-profile optics to an absolute co-witness height when paired with standard AR-15 iron sights.

Precision-machined from high-grade aircraft aluminum, the MNT-RS08S3 features a see-through arch design along the lower body rail channel. This skeletonized geometry allows unhindered use of underlying iron sights while significantly reducing unnecessary front-end weight on the receiver top rail.

Equipped with an ergonomic, quick-adjust side thumb nut and locking plate assembly, the UTG 3-Slot Compact Riser mounts securely to any standard MIL-STD-1913 Picatinny or Weaver rail interface without requiring special tools for field mounting. Finished in a matte black hard-coat anodized surface, it provides dependable zero retention and optimal sight alignment for compact tactical builds.

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

Fitment Matrix: Direct fitment for standard MIL-STD-1913 Picatinny and Weaver top rails. Ideal for micro red dots (e.g., Aimpoint Micro footprint, Vortex SPARC/Crossfire, Holosun micro dots) requiring an 0.83" rise to achieve absolute co-witness alignment with AR-15 iron sights.

1. Ensure the host firearm upper receiver is completely clear, magazine removed, and chamber visually and physically verified empty.
2. Clean and degrease the target receiver Picatinny rail section before positioning the riser mount.
3. Place the MNT-RS08S3 riser onto the receiver rail, pushing forward toward the muzzle so the cross-bolt seats firmly against the Picatinny recoil slot face.
4. Hand-tighten the side thumb nut firmly, then use a coin or flathead tool to apply a final quarter-turn lockup. Mount your red dot sight onto the elevated 3-slot rail section and torque optic screws to specifications.
