You don't have to, your character only has to deal with the immediate situation in front of him. If some Indians bring their magic thunder sticks and try to conquer and enslave your character, your character will understand that situation quite well, and he would adapt just as the Indians in our history did, perhaps a little better, because our history Indians weren't quite as advanced as the Bronze Age with Europeans first came over. I'm sure the Ancient Greeks, Egyptians and others could figure out how to make such things as muskets or printing presses, once they have samples to copy and work from. The difference between Renaissance and Bronze age is really very little. If Bronze agers capture a black smith or obtain a printing press or a gun and know what it does, they could probably build one in short order. Those devices are not beyond their comprehension, they just haven't thought of them. It is easier to copy than invent.
Problem of copying firearms is obtaining materials of sufficient quality, and having manufacturing techniques of similar high enough quality. Firearms require quite high technology (metallurgy in particular, but also in chemistry, and also in mechanisms and machining, and eventually, in repeatable manufacturing processes). Manufacturing firearms will require advancing a sizable industrial base.
