I've seen alot of these apocalypse arsenals around the wiki, so I thought I'd just post how my AR15 and AK would be set up for an apocalypse.
I'm gonna go over the specifics and some of the stuff I would have aren't on the wiki like the B.E Meyers flash hider.
Lower receiver: LMT
Upper receiver: BCM mid-length upper.
Grip: Tango Down BG16
Stock: Magpul UBR
BUIS: Troy Battlesights
Bolt carrier group: BCM
Light: SureFire X300 Ultra
Optic: AimPoint T1 Micro Red dot
B.E. Meyers flash hider
Trigger group: Geissle SSA trigger
Charging handle: AXTS Raptor ambidextrous charging handle
Rail system: DD Omega 12
Same with the AR.
Model: Century Arms C39 v2
Stock: Magpul CTR
Optic: EoTech XPS3
U.S. PALM Ak mags
Trigger group: Brownells
Internals are kept the same except the trigger group.
And that's pretty much the set up's I'd have for my AR and AK in the apocalypse
