The Ncstar AR15 3/4" Riser Gen2 - Long is a versatile rail accessory designed for AR15 and M4 platforms that work with Weaver, Picatinny, or MIL-STD 1913 rails, delivering a practical solution for optimizing optic mounting height. This 3/4 inch elevation increase provides a more comfortable cheek weld and shooting position while enabling lower-profile optics, enhancing accuracy and speed in dynamic shooting scenarios. The Gen2 Long riser features a hollow channel running the length of the rail, reducing weight and offering a see-through sight channel that preserves iron sight alignment when needed. Built to fit securely on compatible rails, it seamlessly integrates with existing handguards to maintain a clean, functional rifle setup. Ideal for instructors, hunters, and sport shooters seeking improved eye relief and better cheek contact without sacrificing rail integrity, this Ncstar accessory supports a stable mounting platform for red dot, holographic, or magnified optics. With its durable construction and practical geometry, the AR15 3/4" Riser Gen2 - Long helps you achieve faster target acquisition and a more natural shooting posture across a wide range of applications.
