This milled steel 24" underrib requires final polishing, to remove mill marks, before installation and finishing. It will fit a 40" or shorter barrel, assuming a 16" forend length (24" + forend length = barrel length).
Sometimes soldered to the bottom flat of your 7/8" octagon barrel, we recommend using our Stay-Brite brand solder, to tin the mating surfaces. Assembly with solder requires simultaneous assembly of the rib, barrel, middle and front ramrod pipes.
We prefer to mount this rib with our 5-40 thread special rib screws, to allow easy assembly, browning, and soldering of the rod pipes. We also offer 6-40 and 6-48 rib screws.
Our gunsmith will install this rib, and ramrod pipes, at extra cost, when you order the barrel, plug, rib, ramrod pipes, rib screws, and installation labor on the same order. When replacing an old barrel, we must have the old barrel, or old stock, or both, to be certain of correct dimensions.
