The first .308 Rifle with the KeyMod system has been released by Mega Arms with their new MKM Maten. The Keymod handguard with upper receiver will only fit their proprietary lower receiver. However, later this year they are due to release a 5.56 version Keymod upper, which will fit any standard dimension AR lower. Mega is looking at about a one year lead time to get their current orders fulfilled for 5.56 lowers.
