Before the Revolution rifles were rare anywhere. The most common gun was some sort of smooth bore, and those on a typical smoothbore stock.
Rear sights were placed on the Carolina trade gun, and rear sights on smoothbores go back to matchlock days. Most guns were made without them.
All men over sixteen and physically fit enough were in the militia, and expected to be armed.
Since even a inexpensive gun cost around a months wages many men got an arm from public stock
Few people hunted, and most that did it was small game, so a smoothie just made sense.
One had to have a valid reason to invest in a rifle, if there was a maker near. And likewise anything more then a plain work-a-day smoothie.
Only the rich hunted for recreation.
And snares or fishing could augment your dinner table pretty well
