    In my opinion the best current bayo, arrived in fantastic shape, and with the desirable markings. Super service from Venture. Thank you for the deal.

    I have another Ontario Knife Co bayonet and I gotta say this one seems better for the money. It uses Molle straps compared to an Alice clip to attach to your gear, so that’s pretty nice if you’re looking for a more modern setup. It’s also in coyote brown so it’ll match with any type of gear. Overall a solid knife but without a full tang however.

  3. G (verified owner)

    Came in excellent shape. I almost wanted something saltier and used been-there-done-that look but new is nice too! What’s there to say? It’s a big knife made of good steel. Fits all the lugged AR family very well but unfortunately the handle is too fat to fit my Mossberg M590 with factory bayo lug. All in all a most excellent purchase!

    Ordered one while the description says it is used, mine looks like it’s NOS. Certainly worth everything I gave for it. Way better than advertised. You got my vote for sure.

    This is not the M7 or M9 Bayonet. It is more similar to a USMC Kabar fighting knife, that is also a bayonet.Â
