Izayo, i suppose you will work on making some of the attachments visible in the future? I noticed that most guns don't have the bipod model or foregrip when equipping them.
Aside that, everything works perfectly, one very small detail i noticed is that when you equip a silencer, it is still possible to see some "light" reflection of the muzzle flash on the front of the weapon, even though there is no muzzle flash, it's barely noticeable and shows up only on higher settings, but i just wanted to let you know in case you wanted it to be perfect ^^
