Cadillac of AR15/M16 bayonets
While I prefer the old M7 to the M9, the OKC3S trumps them all. This thing is imposing, solid, and holds up to USMC world class use and abuse.

Basically a KABAR with a locking lug. Useful even as a solid field/combat knife. You will be impressed.

Super Sweet!
The Marines did a study on how large and how long a bayonet would have to be have the stopping power of a .357 mag+p round. This is the result. We used ours to pry apart pallets and we inflicted all other kinds of abuse. When guarding POW's that Bayonet on your rifle or shotgun showed you meant business.
