Hmm, it wouldnt work so good I think, because, if you slap a original AK47 mag in the gun, it turns into a AK47, just with your model and ironsights/scope.
I'm in the process of putting an RPK-74 test model into the game. I've figured out importing from 3DS / texture swapping to get my premade and premapped textures onto the P3D model, and BRSSeb's weapon tutorial (www.ofp.info/brsseb) should take me the rest of the way.
After I can confirm that the RPK-74 works, I'm going to make the SR-47/74 weapons with full LOD modeling.
Are you making the RPK-74 or RPK-74M (Black, modern), with drummag (unrealistic) or 45 round mag.
