NcStar AR-15 Quick Release Picatinny Rail 3/4" Riser

The NcStar AR-15 Quick Release Picatinny Rail 3/4" Riser is a Generation 2 optic mounting accessory engineered to elevate your sight platform for improved ergonomics and shooting position. This quick-detach riser raises Picatinny rail-mounted optics by three-quarters of an inch, bringing low-profile optic mounts to a more natural cheek rest height without requiring a complete upper receiver swap or permanent modifications.

The Gen2 design features an updated locking quick release mechanism with a shorter, more ergonomic lever compared to the original version, while reducing overall weight. The riser mounts directly onto any Picatinny rail surface found on AR-15 and M4 platforms, allowing rapid attachment and removal without tools. This is particularly valuable for shooters who maintain optics across multiple platforms or need to transition between iron sights and magnified optics during transitions or malfunction drills. Weighing just 0.32 pounds, the riser adds negligible mass while delivering measurable improvements to sight picture and trigger control alignment.

This accessory serves law enforcement, military personnel, and serious civilian shooters who require modular, repeatable optic positioning. Whether configuring a duty rifle, patrol carbine, or competition build, the 3/4" height is a practical middle-ground solution—substantial enough to clear most rifle-mounted lights and laser systems, yet compact enough to maintain a low overall sight radius. The quick-release design eliminates the frustration of permanent mounting while the refined Gen2 lever ensures consistent, zero-preserving engagement cycles.
