This is a custom machined, billet aluminum handguard for a M9 Bayonet with a bead-blasted finish. It will fit Lan-Cay, Phrobis, and Ontario M9 bayonets and probably the M9 imports as well. May have a few small scratches or scuffs. It may need additional finishing to meet your particular specifications.
The last 2 pictures show what this looks like installed on a Phrobis bayonet (handle and blade are not included).
This is a limited production item that was made years ago by a company that started to make bayonets, but never finished the project. It's the same company that made the billet black handles that were sold years ago. USA Made.
