This excellent copy of the M-9 bayonet isnâ€™t the real thing, but youâ€™d be hard pressed to tell, and it sure wonâ€™t matter to whoever is on the other end of your bayonet. 12-3/4 inches overall, with a 7-1/4 inch blade. The blade has a blood groove and a saw-tooth back. Comes with a plastic sheath, a wire cutter and a front pouch for a sharpening stone. Available in olive drab or tactical black.
