Ka Bar Pistol Bayonet!
Ka Bar and Laserlyte have come up with an unusual product. This is a knife mounted on a rail receiver that you can slide onto any medium or large pistol with a rail.
Here is the Laserlyte information:
Be the first to own a Pistol Bayonet that looks as good as it works. This razor-sharp Ka-Bar® blade fits any medium to large pistol with a rail and slides on and off easily with the press of two buttons. The blade handle is constructed from 30% glass-filled nylon for strength and durability. Its carbon steel blade is sharpened to a fine edge and finished with a black Teflon® coating for protection. A LaserLyte original, the Pistol Bayonet is ready for any situation—or just looking cool on your favorite gun.
