For the purpose of this thread the requirments would be a ML gun of the pre cartridge era, fixed open sights, prb this this is about the guns and type of gear on the guns and fired from the guns that seperates the old from the new, it has nothing to do with how we get from the house to the woods or whether the barrels are made of iron it is about form and function and staying as close as posible to the technology of the past, the pre-cartridge era cut off will help avoid adding or attempting to add modern stuff under the loose association or commonality by evolotion loophole, it may not suit everyones needs or desires but that is exactly what it is all about.....something special.
and had you read the post you quoted the last sentence would have answered your question.
