Don't wanna sound like a killjoy but we've already got Firearm threads in ST and OSST, don't know if mods are gonna let this one live.
that said....I've got a small collection, but I'm happy with all 3.
Russian Mosin Nagant
CZ452FS with BRNO match globe sights (this thing is just absurdly accurate, it'll shoot under half MOA with Wolf MT)
and my home built AR15 (pictured Below)
