I wouldn't trust renters insurance to cover firearms, I go over SPECIFICALLY with the agent what I have and that if it gets stolen, I want it replaced, and not just FMV but what I originally paid for it. It has required some thorough documentation that might make some shudder, but it helps me sleep at night.
With all the ammo and firearms it would take 2 big dudes to move the thing and down 3 flights of stairs good luck!
now I ended up with a snap safe that is assembled in a closet with the door smaller than the safe itself
You sir, are a specialist in the art of discovering a welcoming outcome of a particular situation....not a mechanic.
