I like the model, but there are several serious issues with the mod.
a) It got individual materials for each material slot, original Suomi model from Sketchfab got a single material for the whole gun that could have been reused for the magazine as well, saving you some disk space. b) You don't need to replace the materials you have no need for, you can left the rail material as is after removing the rails. c) just imo, but 4k isn't really that necessary unless you are combining materials, and as mentioned previously, everything is contained within a single map and can probably be downscaled to 2k.
