I have for sale a Zero Tolerance ZT-9 Bayonet in like-new condition. These are discontinued and hard to find of course. If you know what this is, then you know what this is, but here is the retail product description: "The strongest production knife on the face of the earth. And that's vital. Because if it comes down to bayonet time, there's no room for compromise. The ZT-9 doesn't. A sturdy S30V stainless steel blade, a full 1/4 inch thick, is paired with Ranger Green G-10 scales. The ZT-9 mounts on the M-16/M-4/AR-15 series of rifles. When mounted, a full six inches of blade extends beyond the muzzle, more than today's standard-issue bayonets. Comes complete with sheath for use as a field knife. A Strider-ZT collaboration." Bayonet comes as pictured with sheath; what you see is what you get. $400 cash or Paypal. I can do local pickup in the Atlanta area, but I'm also willing to ship at your expense. Put that bayonet lug on your AR (or Mossberg 590-A1) to good use!
