We were talking with a firearms parts manufacturer and found it funny that despite them utilizing the KeyMod system, he noted that he didn't know what it was all about. We see this same acknowledgement from many people and just want to say KeyMod is simple stupid. This isn't meant as a jab or a superior understanding of the matter. In the end it is a basic concept that people shouldn't over-think.
The slotted attachment points take away material to make for a lightweight modular attachment system. The design is open source and the inset slots allow for a low profile attachment of compatible accessories that anyone can develop. KeyMod is a newer development in firearms handguards, but similar concepts have been utilized in many other mounting platforms including rack shelving and in the case above a power strip. Some alignment is required and some make light of the similarities to rifle handguards and these other platforms, but the simplicity of it should be embraced. Obviously many in the industry are picking up on it even if some are over-thinking it as well
