Since the passing of our good friend, Tom Ondrus, there has been a gap in the building supplies for double rifles. In an attempt to fill the most difficult part of this void, I have had some ribs machined that are very similar to the ones Tom had for sale. They measure 24 inches long and will work for 26 inch barreled guns if monoblocked. If the rib section is removed from your monoblock, then these will work for 24 inch barrels. The standing quarter rib and the front sight sections are all built right in and this makes a neater and much easier installation.
The quarter rib section is just over seven inches long, then there is a concaved mid section that is 15 inches long and then a 1.5 inch front sight ramp section. They are beveled on the bottom corners at 45 degrees. I have sold many of these and people are very happy with them. Current cost is $100.00 plus $10.00 for shipping. I can send multiples for the same cost. You can PM me or email me at : roberthynden@yahoo.com
