For many years, the Picatinny rail dominated the market for mounting accessories like lights, lasers, and foregrips on firearms. Despite its widespread use, users often criticized its additional weight and the discomfort caused by its “cheese grate” texture. Both the Picatinny and Weaver rail systems were effective for scopes but less so for other accessories, highlighting the need for innovation.
This demand led to the development of the next-generation mounting systems: KeyMod and M-LOK. Unlike their predecessors, KeyMod and M-LOK use a slot-based system rather than rails, providing a smoother surface and versatile mounting options. Since their introduction in the 2010s, both systems have seen increasing popularity, but which is superior?
Exploring KeyMod
Developed through a collaboration between VLTOR Weapon Systems and Noveske Rifleworks, the KeyMod system was introduced to the public in 2012. As an open-source design, it allows any manufacturer to use the system to produce compatible accessories and rails.
KeyMod accessories connect directly to the handguard without the need for a separate Picatinny rail. This direct attachment is made possible through a key-hole shaped slot system, simplifying the mounting process.
How to Mount KeyMod Accessories
To mount KeyMod accessories, align the KeyMod nut, ensuring the protruding side faces the muzzle. Insert the backer nut into the larger hole of the KeyMod slot and slide it into the narrow section. Secure by screwing in the accessory tightly.

Exploring M-LOK
Introduced by Magpul Industries in 2014, the M-LOK system (Modular Lock) provides a similar slot-based mounting solution. Designed to improve compatibility with polymer-based accessories, M-LOK requires a license for manufacturers, unlike the open-source KeyMod.
How to Mount M-LOK Accessories
M-LOK accessories use a rectangular T-Nut that fits into a corresponding slot. Properly align and seat the T-Nut within the M-LOK slot, ensuring the accessory is flush with the mounting surface. Secure by rotating the T-Nut 90 degrees and tightening to the appropriate torque.
Comparison: KeyMod vs. M-LOK
In 2016, the United States Special Operations Command (USSOCOM) conducted tests to compare these systems, focusing on repeatability, endurance, and rough handling. M-LOK performed notably better in repeatability tests and was more reliable in drop tests, leading to its selection for specific military programs. Despite these results, KeyMod remains a viable choice for non-military applications.
Final Thoughts
Understanding the nuances between KeyMod and M-LOK is crucial for firearm enthusiasts aiming to customize their equipment. As technology progresses, staying updated with the latest advancements in rail systems will enhance your ability to tailor your gear effectively.
