as an american, and as a proofreader for this chapter, i am legally obligated to identify the guns on page 7. starting from the wall on the right going top to bottom we have a Minebea PM-9, P90, MP7, the lighting covers up some important details so its hard to say for sure but it looks like some variant of M4, the pistols are unidentifiable due to the light covering them up too much
now for the left wall, again top to bottom: i dont know if the top one is a real gun, it looks like an M14 EBR had a baby with a SIG 552, its dust cover/upper is too squared off to be any model of FAL that i know of but that chunky handguard is really unusual for more conventional Intermediate cartridge firing rifle, then below that is a sig p365, then a 2011 or similarly modified Kimber 1911 then from right to left on the three rifles its likely an HK416, then an m16a1 or ar15, i cant see if it has a forward assist to differentiate between them, then the last one has an ar15 lower and the gas block on the barrel is quite far out leading me to believe its quite long so maybe an MK11 mod 0 or SR25
there's also an incredibly short belt of some variety of ammo but none of the guns here are belt fed so im unsure exactly what its there for, and it looks like the rounds in the belt aren't nearly as tapered as most modern Intermediate cartridges so im unsure of exactly what caliber rounds they are, they look incredibly long, so maybe its a belt of 50 BMG for an M2 browning or something that's stored off screen somewhere, they still dont look tapered enough to me but that would be the round closest in terms of approximate size that sees any real use in belts
