Are Tall Mounts a Fad? [ THE AR FILES | Optic Height ]

Published on August 22, 2024
Duration: 13:30

This video provides a comprehensive overview of optic mount heights for AR-15 platforms, explaining the trade-offs between shorter and taller mounts. It details common heights like absolute co-witness (1.42 inches), lower 1/3 (1.57-1.7 inches), 1.93 inches, and 2.26 inches, discussing their impact on cheek weld, recoil management, height over bore, and compatibility with night vision. The presenter emphasizes that the 'best' height is subjective and depends on intended use and personal preference.

Quick Summary

Optic mount height on an AR-15 significantly impacts shooting dynamics. Shorter mounts (1.42") offer better cheek weld and less height over bore, ideal for prone shooting. Taller mounts (1.93"+) promote a heads-up posture, aid night vision, and offer better long-range zero consistency, but can reduce cheek weld and increase offset management.

Frequently Asked Questions

What are the main differences between short and tall optic mounts on an AR-15?

Short mounts (around 1.42") offer a positive cheek weld, minimize height over bore for close range, and are comfortable prone. Tall mounts (1.93"+) promote a heads-up posture, improve night vision compatibility, and offer better consistency at longer ranges, though they can compromise cheek weld and increase height over bore.

What is the recommended optic mount height for a general-purpose AR-15?

For a general-purpose AR-15, starting with a lower 1/3 (1.57-1.7") or 1.93" mount height is often recommended. These offer a good balance between usability for various shooting positions and compatibility with different accessories, allowing users to find what works best for them.

How does optic mount height affect zeroing and ballistics?

Mount height significantly impacts height over bore. Shorter mounts have less offset, making traditional 25/36 yard zeros effective at moderate distances. Taller mounts require greater offset management and may necessitate different zeroing strategies for optimal performance across a wider range of distances.

Can I use iron sights with taller optic mounts like 1.93" or 2.26"?

Generally, iron sights are not visible through optics mounted at 1.93 inches or higher, and the mounts themselves often obstruct the irons. These taller heights are typically chosen when iron sight co-witness is not a primary concern, especially when prioritizing night vision use or a heads-up shooting stance.
