M-LOK, standing for Modular Locking system, it is a firearms accessory mounting system developed by Magpul Industries that allows for direct attachment to negative space mounting points. It is a competing standard to KeyMod in regards of replacing the MIL-STD-1913 Picatinny rail in some applications. Compared to the Picatinny rail system, M-LOK and KeyMod enables the user to have a slimmer and smoother handguard with accessories mounted only where needed, whereas a Picatinny handguards typically will have Picatinny rail slots for its whole length resulting in a larger handguard diameter with sharp corners.
