Late to the party. I bought a stack on 14 gun....about 12 years ago Green one - not a bad size. 16x21x55. I just use it for ammo (6000rnds+), mags(60+), optics and accessories. That stuff adds up $$$$$. Actual Safe is from Costco, roughly the same size maybe about 6" taller and deeper. Can't compare pricing as everything was cheaper 'Back in the day' but it was around $300.
With recent purchases I am out of room, I need a new safe now.... oh well. Safe is full and I have to find a room for 6 more.
And if anyone whats a 14-gun steel cabinet TSC stores has one for 1/2 price. CABINET $199
