These weapons are a good concept idea but they are lacking the balance, these guns are older guns compared to a simple pistol/rife/shotgun. These guns take a long time to reload, they are powerful though and cheaper to make, why not lower the levels it takes to unlock these guns like the Muskeet? The flint pistol is a good example of a level unlock reduce, that gun takes a while to reload which means you must/can hold onto many of them, why not reduce the level to unlock it? Then there is the mustkeet the very first you can unlock, I do not like the mech. while I hold it the durablity burns as I light the fuse, can you only make it to where the durablity fades by actually shooitng the gun? The mod prodives cheaper weapons to make compare to the revolver that takes 60 metal and a lot of metal to repair but with the durablity being burnt away so fast you might as well make the revolver because you can actually save more metal up within time. The mustkeets metal consumption is awful compared to the simple pistol (revolver).

I'd think this be a good mod for lower tier guns to make before players can head out far up north and get better guns that are more modern.
