Lantac has released a promotional video for its new Keyed Accessory Mount System (KAM). This system competes directly with Magpul’s M-LOK and Vltor’s Keymod systems. Like M-LOK, and unlike Keymod, KAM is a direct-insert system:

As with rail systems over a decade ago, it’s likely that these rail attachment systems will be whittled down to one standard or de-facto standard system. I suspect the two systems designed with polymer parts in mind will have an advantage over Vltor’s Keymod, but Keymod is so far the best established of the three.

Thanks to Dale for the tip.
