Since this rifle is used in dodge builds I decided that putting a sight on it without losing stats might be a good idea. Compact Profile Sight looks weird anyway (plus it isn't compact, xd) and that angled sight that adds +1 concealment is not what I want to have equipped.
So I changed the Base Concealment from 20 to 21.
Spoiler!
Since this gun can reach 100 accuracy if you don't mod the barrel, you can change the concealment value in the mod.
I didn't try that but my guess is that something like 26-27 will work. I didn't do that since that would've made the Short Barrel obsolete.
