Steelwater Heavy Duty 20 Long Gun
3.6/5 Best Safe Score (how we score)
A 453 lb, 20 long gun safe in 12-gauge steel with ten 1.5 in bolts and a maker-rated 60 minutes at 1875°F. I include it because Steelwater's own 12-16 realistic count is what most 24 gun safes really hold.

Who it's for
- Heaviest build in the 24 gun class in Best 24 Gun Safe – 5 Picks and How Many Rifles Really Fit: A buyer with 12-16 scoped rifles who wants the thickest steel and longest fire rating here; the rating is Steelwater's own, and 453 lb needs a ground floor or slab and a delivery crew.
What we like
- Longest fire rating here: 60 minutes at 1875°F (maker's rating) with a heat-expanding door seal
- 12-gauge steel and ten 1.5 in solid steel bolts
- Four corner anchor holes reinforced with extra plate steel
What to know first
- Rated for 20, not 24, long guns; Steelwater says 12-16 is realistic
- Owners report keypads failing after three to six years
