Instead, once you insert a keymod accessory or accessory rail, all you have to do is turn and tighten the lug screw accordingly and make sure the accessory bracket is secured in place. That would be detrimental to performance if that were true. However in this case, you’re not as reliant on a more substantial object fitting into that smaller hole. That’s similar to how the KeyMod rail works. The large hole accepts the locking mechanism as you slide it into the smaller section. Picture the door chain on your home’s front door.

Buyers get full customization ability with this rail as it doesn’t lose out the traditional picatinny quad rail at all. Furthermore, the KeyMod is compatible with a wide range of accessories and does not lose out on any ability to mount desired optics, sights, or ergonomic grips. Its slim rail offers people the opportunity to really have a fantastic grip on the handguard with their support hand which is why recently seen a lot of race guns built out with keymod. When the slightest weight change can affect your aim and stamina, every ounce counts. So why do so many people love the KeyMod system? To start, KeyMod rails are incredibly light. Because of these public partnerships within the 2A industry and community, we’ve certainly witnessed firsthand a boom in the firearm rail industry - a logical benefit to just about every modern day gun owner. The idea behind this was to create standardized modularity, like the picatinny rail, for which engineers could use for free. KeyMod allowed all other firearm manufacturers to create rails based on the same design without needing to pay for any extra rights to do so by releasing their KeyMod Tech Data Package as an open source to the public. If you want to learn more about the testing that was conducted you can see the full m-lok vs keymod Crane report here.

After the drop tests it solidified that keymod slots would not be able to hold up to the military’s desired standards as there were cracked slots and accessories falling off when dropped. M-lok’s point of aim shift averaged only 1.3 MOA. Keymod’s point of aim shift averaged 4.9 MOA. The most significant results presented themselves during repeatability testing. Another 9 mlok rails tested were also from the same companies (three per handguard type). 9 keymod rails tested were from Aero Precision, Midwest Industries, and Seekins. A total of 18 handguards were used to conduct the testing at Crane. No critical comparison of these two rail systems would be complete without mentioning the tests that were conducted by the US Naval Surface Warfare Center - Crane Division, which provides Naval Support Activity via “acquisition engineering, in-service engineering and technical support for sensors, electronics, electronic warfare and special warfare weapons.”Ĭrane released a comprehensive report comparing the keymod and m-lok modular rail systems. Its result was the Modular Lock System, or M-LOK for short. Those slots lived on to help refine Magpul’s line of MOE rail-compatible products. Masada's initial design had an interesting handguard with three slots on the left and right sides of the handguard. You’ve probably seen it in some movies and video games but today we know it as the Bushmaster ACR. M-LOK’s origins come from the 2007 concept rifle that Magpul helped design, the Masada. They also make high end custom rifles that are quite expensive. Noveske has been known to produce high quality competition grade rifle barrels that have also been used by the military. VLTOR is known for manufacturing and selling innovative weapon system accessories. KeyMod began in 2012 as a combined effort from the experts at VLTOR and Noveske. But which one is the better rail system? You can only choose one for your rifle, so let’s weigh the pros and cons of each to determine which is the winner. For the past decade, Keymod and M-LOK have been the most used and most popular options on the market. But did you know that there are six types of rail systems out there for your favorite guns? There is the Dovetail rail, Weaver rail, Warsaw Pact rail, Picatinny rail, Keymod and the M-Lok. They have a couple names: handguards or rails. Today we’re talking about Keymod and M-LOK.
