So, I finally thought of taking a look at Pimp My Gun, so I came up with this, the RKM "Hakkapeliitta". It's not very thought out per se, I only took like 20 minutes to browse through all the parts and find something I liked + adding the text in GIMP.
RKM (RynnäkköKivääri, Modernisoitu) "Hakkapeliitta"
Intended to replace the RK-95 TP in a certain Civ game at some point
