So I found a 50 quality Monsoon and got a bunch of components for it, and I managed to discover some potentially useful information for calculating the stats of items based on their components, meaning that it's possible to put in data for weapons without having to get an exact screenshot of the weapon in question.
So, if you look at the image, a regular, 50 quality monsoon has a value of 6450, and a quality of 690 (like all 50 quality weapons). Now, the change in stats for most components is known, but as far as I've seen how value is determined isn't known. If you compare the regular monsoon to the scoped monsoon, you'll notice its value is 9450, its value has been increased by exactly 3000, which is exactly 3 times the value of the scope, and this holds true for all the other variants as well. The first component you add to a weapon increases that weapon's value by exactly 3 times the value of that component.
Adding a second component does the same, except the total weapon value is now increased by 20%, so a super pneumatic monsoon, which should cost 19200 assuming that its value is being increased by 3 times the value of the added components, is instead worth 23040, exactly 20% more.
So, that means that instead of hunting in vain for a digital scope and making screenshots for all the other possible variants of a 50 quality monsoon, it can just be extrapolated instead. A 50 quality monsoon with a digital scope and pneumatic reloader will have (compared to a base monsoon) a 21 AP firing cost, a 23% crit chance, and will have a value of 18180.
I went and did a cursory test on an assault rifle and it worked exactly the same way, with the exception that the value of the barrel isn't counted when making one, just the value of the frame and the added components. For a tactical vest, the base value is 3 times the combined value of vest and insert, with components adding their value and the extra 20% normally
I don't know whether you're set on getting exact screenshots of weapons epeli, but this could make filling out the wiki a bit easier. You wouldn't need to have exact 50 quality components to have an exact readout of the item's stats. With a bit more information about the relationship between item quality and its stats, you could also make a browser-based crafting calculator so people can figure out what a weapon is like without having to find it and all the components in game themselves.
