Leupold Mark AR Rail Mount | One-Piece Picatinny Riser Base LU181347

The Leupold Mark AR Rail Mount is a precision-machined riser designed to fix the most common ergonomic hurdle on AR-style rifles: improper optic height. In tactical shooting, a mount that sits too low forces a strained cheek weld and ruins your sight picture. This one-piece aluminum solution raises your platform to a 0.7-inch center height, ensuring your eye aligns naturally with your scope for faster target acquisition and better consistency.

Precision shooting requires a neutral head position and a consistent eye box. This riser is engineered to provide that perfect optical axis relative to the bore, eliminating the fatigue caused by "scooting" into a poorly positioned scope. By using integrated recoil lugs and a heavy-duty five-bolt clamp, the mount creates a massive surface-contact area that distributes the load of every shot, preventing the micro-movements that typically kill your accuracy.

Machined from 6061-T6 aluminum and finished with a durable hardcoat anodize, this mount is built to survive the violent cycling of a gas-operated rifle. The three-lug interface ensures your zero never shifts, even under sustained fire, while the total weight of 6.05 ounces keeps your rifle balanced and fast-handling. It’s a professional-grade upgrade that turns a standard receiver rail into a rock-solid tactical interface.
