I finally found a scope and was looking forward to attaching it to my sniper rifle. But the sniper rifle has no "Modify" option in my game!

I went looking through the items.xml and noticed the marksman rifle is called "MR10" but it does appear to have all the requirements for attachments. Is it just my game is it something new?
This is of course A17E b208
