I have no desire to ever build a rifle myself but I do occasionally look through this forum. One thing that I notice is everybody builds there conversions using the monoblock system. I can understand how this may be easier if you don't care about the original shotgun barrels but what if you want to save them? I was just reading a thread where the builder wanted to save the original shot barrels but didn't have the knowledge or desire to build a new monoblock. Wouldn't a shoelump set of barrels be much easier to make? I know that no one besides Greener is using this system these days but it was used on heavy doubles back in the day with great success.

Just curious and thought maybe this could help someone else out.
