As I walked through the SHOT show and the acres of AR accessory makers, one trend in rail systems became obvious. There is a move in the industry to standardize the modular rail attachment system with the keymod system. Manufacturers such as Knights Armament Corp, Noveske, and Mega are moving toward this new standard. There was even a new rail systems for the AK platform that is based on keymod. Some of the larger names in rail systems such as Daniel Defense and Larue Tactical have not yet released a keymod-based rail system. Time will tell if this is another fad in rail systems or something that will be adapted industry wide.
Here’s a link to the Noveske NSR rail with some great close-ups of the keymod system.
