We at Ithaca are currently fine tuning our O/U.
12 gauge and 20 gauge will be on the same frame!
For all of you 16 gauge diehards, yes we will make that as well
28 gauge will have it's own frame!
We are in the developing stage of a new side by side.
All gauges will be built on their own frame!
All guns will be manufactured and assemblied in the near future (we will not be pushed to release a product, just to release a product).
All of our guns are manufactured and assembled under one roof.
We will post pictures on our web site with more details soon!
