870 Barrel on a Norinco Hp9

mine took a little work.. 2 different remington barrels

I had to open up the lug recess on the breech end of the barrels a couple of thou with a dremel as it would not lock. Still works and headspaces fine on a remington receiver, as I only made the recess DEEPER, not longer.

A mossberg manufactured 870 slug barrel went on fine, no alterations

good luck
:)
