As the title says I'd love to see an Add-On mod for the Valkyria (as-val) to give it a new barrel and stock that make it look like the SR-3.

Maybe you'd be able to rip the models for the Heather SMG to make the stock and potentially the barrel/foregrip as shown in the image below.

Also if possible I'd also want too see a picatinny rail (potentially using the ak side rail?), and stock like the image below, which could probably be made by messing with the default stock,
however that might be getting too greedy when asking for free stuff.

Cheers for if someone decides to do it (or points me to a mod that already does this stuff)
