I've got an extra pair that I don't need what ya got to trade? I know the price on these things are all over the place from $25-$90. Mine are in great shape out of a BPR marked WWII gun. Hint.....I do want jbaums newest manual.
Try Robert at RTG Parts.....he has them back in stock new with rivet-sets at $47.50 plus shipping. These are the earlier style where you have a left and a right side rail (for WWII style MG42s).
