Firearms definitely should be more accessible to newer players, but making it so everyone can craft them is the wrong way to go (in my opinion). As I've stated, selling things (here: firearms) should be much more rewarded. As of right now, you'll barely get any money selling guns as everyone wants you to sell them for the material price. You're kinda not allowed to get any kind of profit. If there would be fewer people crafting guns (for themselves), people would have fewer demands in terms of prices as they wouldn't have anywhere else to go. Yes, that would open up to monopolies, however, that would be the only way to give them the ability to set a price from which they actually make adequate profit.
