A picatinny/weaver style mount for a folding bayonet provides a cradle with set screws, for affixing the folding bayonet to the mount. The mount can be affixed to any picatinny/weaver style rail that is on the barrel of a rifle, automatic weapon, shotgun, or other long firearm. Below the cradle, is a rail mount that provides a main bolt for the mount, which may be secured with an Allen wrench and released with one hand. On the left side and the right side of the mount, picatinny rails are provided for securing a flashlight, sighting laser, bipod, or other attachments.
