Picatinny Rail Bayonet Mount
Now you can mount a bayonet to a modern extended handguard like a quad rail, KeyMod or M-LOK. All you need is a Picatinny rail with at least three available rail slots. The Universal Bayonet Mount is super lightweight, low profile and weighs less than a standard A2 front sight.
Weighs even less than a standard A2 front sight at around 4 oz. Constructed of lightweight and strong aircraft grade aluminum alloy. Hard coat anodized for durability. Allows you to adjust the extension of your bayonet.
Works best on rifles where the space between the handguard and the end of the barrel and flash hider is 9” or less.Link to parts manufacturer
