Leapers UTG Riser Mount 1 13 Slots Fits Picatinny Black Finish MT RSX1L UPC 4717385551923

Product Description

The Leapers UTG Super Slim Picatinny Riser Mount (MT-RSX1L) in Black is an extended, precision-machined optic elevation platform designed to elevate red dot sights, scope rings, laser aimers, and tactical optics on AR-15 and rifle platforms. Featuring a high 1.0-inch profile rise and an extended 13-slot Picatinny rail length (5.5 inches), this riser provides a continuous elevated mounting surface ideal for running full-sized optics, red dot and magnifier combinations, or thermal scope systems.

CNC-machined from high-strength 6061-T6 aircraft-grade aluminum, the MT-RSX1L utilizes continuous skeletonized weight-reduction cuts along the main body channel to minimize overall mass while maintaining structural rigidity and zero retention under heavy recoil. The 1.0-inch height elevation brings low-profile micro red dots up to a comfortable lower 1/3 co-witness height when paired with standard AR-15 iron sights, facilitating a natural, heads-up shooting posture.

Equipped with locking Torx side screws and integral square recoil stops, the UTG Super Slim Riser locks securely onto standard MIL-STD-1913 Picatinny receiver rails to prevent movement or point-of-impact shift. Finished in a non-reflective Matte Black Hard-Coat Anodization, it serves as a durable, snag-free elevated rail system for modern tactical optics configurations.

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

Fitment Matrix: Direct fitment for standard MIL-STD-1913 Picatinny receiver top rails. Accommodates red dot sights, magnifier mounts, thermal optics, and standard Weaver/Picatinny scope rings requiring 1.0" of additional height clearance for lower 1/3 co-witness or heads-up shooting.

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 MT-RSX1L riser onto the receiver rail, pushing forward toward the muzzle so the integral recoil locking lugs seat firmly against the Picatinny slot faces.
4. Torque the Torx locking side screws evenly to 25–30 in-lbs using the included Torx key. Mount optic rings or red dot sight onto the elevated 13-slot rail section and torque to optic specifications.
