I've got 2 MLOK rails for an HK MR 7.62 up for grabs. The first one is the factory MLOK rail that came with the rifle from the factory the color is black and I'm asking $200 shipped obo. The second rail I have is a Geissele FDE factory blem rail that is new and I'm asking $450 shipped obo. I can accept payment via PP plus fees, zelle or venmo. Let me know if you have any questions.
