Speculation on my part, as I haven't seen your gun, but it sounds to me as tho you have removed the forend wood, possibly by removing a screw or two, and left the forend iron in place. The forend, if it doesn't have an external latch on the bottom side, snaps into place with a spring loaded latch of a couple different designs. The forend on these is removed by pulling downward on the forend, and some are pretty stiff, a good thing. I suggest since you have removed the wood, try putting a screwdriver between the barrel rib and the "rod" that you spoke of and pulling downward gently. I bet the "rod" pops off the stud it is snapped on to and you can reinstall the forend iron into the wood and leave it there. Goatwhiskers the Elder
