Mounts and Risers

What’s the difference between optic mounts and risers — and why do they matter?

Mounts and risers control the placement and height of your optics and accessories — which directly affects your ability to shoot faster, see more, and maintain a solid cheek weld under pressure. A riser elevates your red dot or scope to a height that matches your preferred shooting posture or gear setup (e.g. night vision, gas masks, plate carriers). Mounts, especially QD or cantilever options, provide rock-solid attachment points while also managing eye relief, alignment, and repeatability. Whether you're dialing in absolute co-witness or running 1.93” for passive aiming, these components aren’t optional — they’re foundational to building a rifle that works around you, not against you.

Frequently Asked Questions about Mounts and Risers

What riser height should I use for a red dot sight?

The most common heights are absolute co-witness (1.5") and lower 1/3 (1.57"). Higher risers like 1.93” and 2.26” improve head position for night vision or plate carrier use, while reducing neck strain during extended shooting.

Do I need a riser or a dedicated mount?

It depends on your optic. Some red dots come with built-in mounts and just need a riser. Others require a dedicated mount to attach securely and achieve the right height. Always check your optic’s base and compatibility first.

Can a QD mount hold zero after removal?

Yes — quality quick-detach (QD) mounts will return to zero if reinstalled on the same rail slot. They’re ideal for optics that may need to be swapped in the field or removed for transport without re-zeroing every time.

Are risers compatible with magnifiers?

Yes. You’ll want your red dot and magnifier to sit at the same height for proper alignment. If you’re running a 1.93” red dot riser, use a matching height magnifier mount to maintain a consistent sight picture.

What’s the benefit of a low mount for optics?

A low mount can also have specific benefits as opposed to higher mounts. Lower mounts can provide a much better cheek weld and stability while reducing zero complications which come naturally with increased height over bore.

Can I stack risers to achieve the right height?

Stacking risers is not recommended. It can introduce instability and increase the chance of zero shift under recoil. Instead, choose a single riser or mount designed for your preferred optic height. But yes, if you really want to, you can.

Are there specific mounts for night vision compatibility?

Yes — mounts at 1.93” or higher are commonly used for passive aiming under night vision. These provide a more upright head position and keep your optic aligned with your NODs when shooting through a tube.

Will a riser affect my optic’s zero?

No — the height of the riser doesn’t affect zero directly, but it does change converging distances. When you switch to a different mount height, you will have to adjust your zero.
