Primary Arms MicroPrism Straight Riser - 1.93"

• 1.93-inch optical centerline: Raises a compatible MicroPrism setup to a taller sight height that supports a more upright, heads-up shooting position and can feel quicker in close work.
• Straight riser format: Keeps the optic aligned without introducing cant, which suits shooters who want a simple, centered mounting solution for a prism optic.
• Aluminium construction: Combines low weight with the rigidity needed for a mount component, helping preserve handling while providing a stable interface.
• Aimpoint Micro footprint compatibility: Fits into a widely used mounting pattern, making it easier to integrate with compatible MicroPrism mounting hardware.
• 0 MOA configuration: Maintains a neutral mounting angle, which is appropriate for general-purpose carbine setups where no built-in elevation bias is needed.

About the Primary Arms Mounts Series

Primary Arms Mounts is a broad accessory family built to support the company’s optics lineup with practical mounting solutions for red-dot optics, magnifiers, scopes, rings, and risers. Within the range, Primary Arms offers everything from cantilever scope mounts to dedicated risers and optic-specific interfaces, giving shooters a consistent way to configure rifles around different sighting systems. The series is aimed at users who want straightforward compatibility and sensible geometry rather than unnecessary complexity.

A notable strength of the lineup is its variety. The catalog includes mounts for Primary Arms MicroPrism optics, flip-to-side magnifier mounts, and options built around interfaces such as M1913 Picatinny. Depending on the application, the series also includes cross-bolt and thumb-screw release styles, along with fitments for 1-inch, 30mm, and 34mm scope tubes. In practice, that makes the Mounts series relevant to both general-purpose carbines and more specialized tactical optics setups, with each design focused on secure attachment, sensible height options, and compatibility with the optic it is meant to support.

About the Primary Arms MicroPrism Straight Riser - 1.93"

The Primary Arms MicroPrism Straight Riser - 1.93" is a dedicated height-raising accessory for the Primary Arms SLx MicroPrism Optic System. Its main role is simple but important: when paired with the factory MicroPrism mount arrangement, it brings the optic’s centerline to 1.93 inches. That taller height changes how the rifle meets the shooter, encouraging a more upright head position that many users prefer for faster target pickup and less neck compression during extended use.

The straight riser layout is especially useful for shooters who want a centered, no-nonsense mounting solution instead of an offset or canted arrangement. On carbines set up for practical shooting, defensive use, or training, that can make the sight picture feel more natural when moving between targets. The added height also suits setups used with night vision devices or protective equipment such as CBRN gear, where a lower optic position can force an awkward cheek weld.

Built from aluminium and finished in black, this riser is designed to match the durable construction expected of a hard-use optic mount component while keeping weight low. Its 0 MOA geometry preserves a neutral optic angle, and the Aimpoint Micro mounting standard gives it compatibility with a common compact-optic footprint used in this part of the market. The result is a compact riser that solves a specific fit and ergonomics problem without complicating the rifle.
