Why KeyMod SUCKS

Published on June 27, 2017
Duration: 11:01

This video critiques the KeyMod accessory mounting system, arguing it is 'backwards' due to its design which resists recoil but fails to secure accessories against forward impacts. The presenter demonstrates how a simulated corner impact can dislodge KeyMod-mounted accessories, particularly highlighting the risk under night vision when reliant on rail-mounted illumination. The video contrasts this with the more secure M-LOK system, showcasing its superior retention capabilities.

Quick Summary

The KeyMod accessory mounting system is criticized for being 'backwards' because its design, intended to resist recoil, fails to secure accessories against forward impacts. This can lead to critical equipment like weapon lights dislodging, especially under night vision. M-LOK offers a superior, multi-directional lock that resists both recoil and impacts.

Frequently Asked Questions

Why is the KeyMod accessory mounting system considered 'backwards'?

KeyMod is considered 'backwards' because its design prioritizes resisting recoil by pushing accessories forward into the rail slots. However, this design fails to adequately secure accessories against forward impacts or directional movement of the firearm, leading to potential dislodgement.

What are the risks of using KeyMod accessories, especially under night vision?

Using KeyMod for critical accessories like weapon lights or IR illuminators poses a significant risk, particularly under night vision. A forward impact can dislodge these essential components, leaving the user in a compromised tactical situation.

How does the M-LOK system differ from KeyMod in terms of security?

M-LOK offers superior security through its design, which uses two locking tabs on each side and a central protrusion that engages the M-LOK slot. This provides a multi-directional lock that resists both recoil and forward impacts far more effectively than KeyMod.

What is the main takeaway regarding KeyMod versus M-LOK?

The main takeaway is that M-LOK is a more secure and reliable accessory mounting system than KeyMod, especially for tactical applications where impacts and directional forces are common. KeyMod's design is fundamentally flawed for resisting anything other than recoil.
