I just put mine on a few hours ago. I used tin snips, a Dremel and a flat head screw driver to remove everything. Mine didn't come with any installation instructions. Maybe they just over looked it and forgot to put them in the box. The delta ring side of it came off pretty quick. The sheet metal piece by the front sight was a pain in the rear to remove, harder then I thought it would be. But everything went well. I'm definitely glad I went with the Centurion C4 Carbine Cutout Rail. The few extra inches are definitely noticeable and worth it to me.
NYH1.
