This is true. Since it was shipped direct from Lan-Cay, you could always call there and ask them if you could send it back for one with a standard scabbard. They are assembling the M9-LW bayonets in whatever configuration the buyer requests. I've seen examples with standard or MOLLE scabbards, Green or black, old grip or ergonomic grip. I've even seen examples on the website with the special unit stamping on the ricasso.
