An Attachment That Can Enhance Your Shooting Experience
Whether you’re a competitive shooter, law enforcement or military professional, or building a dependable home-defense rifle, small upgrades can yield big performance gains. One of the most underrated accessories in rifle setup is the optic riser. While modest in size, the right riser can improve ergonomics, enhance target acquisition, and make your rifle more adaptable to modern accessories and shooting positions.
In this blog post, our team at Guerrilla Tactical is going to break down the purpose of optic risers, the advantages they provide, and why Kastle Optic Risers are a standout choice for shooters who demand durability, functionality, and quality.
What is an Optic Riser?
An optic riser is a mounting platform designed to elevate your optic above the standard Picatinny or M-LOK rail of your rifle. It installs between your optic—whether it’s a red dot, holographic sight, or even a prism scope—and the upper receiver.
Risers come in various heights, typically ranging from 0.5 inches to 2.26 inches, and serve a number of purposes, from improving sight alignment to enabling compatibility with magnifiers, night vision, and other accessories.
Key Benefits of Using an Optic Riser
Improved Shooting Posture and Ergonomics
Optic risers elevate your sight line to align naturally with your eye when you shoulder your rifle. This reduces the need to hunch over the stock or strain your neck, making your shooting position more comfortable and repeatable—especially over long sessions. Shooters wearing helmets, gas masks, hearing protection, or night vision gear will find a higher optic position especially beneficial.
Faster Target Acquisition
A riser positions your optic in your natural line of sight, which means you spend less time searching for the reticle. This leads to faster transitions, quicker engagement, and more efficient shooting overall.
Compatibility with Magnifiers and Additional Optics
Adding a magnifier or thermal device behind a red dot requires proper alignment and rail clearance. Optic risers help raise your primary optic to the correct height for smooth integration with magnifiers, night vision devices, and flip-to-side mounts.
Optimized Co-Witnessing Options
Risers give you the ability to control how your optic aligns with backup iron sights. With the right riser, you can choose between:
- Absolute co-witness, where iron sights align with the center of your optic’s reticle
- Lower 1/3 co-witness, where irons sit just below the reticle, giving a clearer field of view while retaining functionality in case of optic failure
Gear Compatibility for Tactical Use
If you’re operating with a plate carrier, helmet, or other duty gear, standard optic heights can quickly become impractical. A riser keeps your optic visible and usable from a more upright, head-up posture.
Improved Passive Aiming Under Night Vision
For users running night vision goggles (NVGs), a higher optic is essential for passive aiming. A riser helps keep your reticle visible through your night vision tube without forcing an unnatural shooting position.
