Oskar 400F

Gun Cabinet Oskar 400 F

The Oskar 400 F combines the proven quality of the Oskar series with the modularity of the new Flex-Upgrade. For years, the Oskar series has been one of the most popular safes from HARTMANN TRESORE – known for its outstanding security, compact design, and thoughtful details. With the introduction of the Flex-Upgrade, the series has been expanded to a new dimension: maximum customizability.

Whether for hunters, sport shooters, or collectors – the Oskar 400 F offers everything you need for the safe and efficient storage of your hunting firearms and equipment. The classification according to resistance grade 0 according to EN 1143-1 ensures legal compliance and protection against theft. Thanks to the robust construction made of 4 mm thick steel and innovative design details, such as flat hinges and narrow locking bars, the safe is particularly space-saving yet extremely spacious.

The real strength of the Oskar 400 F, however, lies in its modular interior design. Thanks to the innovative modular system, you can customize the interior exactly to your needs – whether long guns with scopes, handguns, ammunition, or accessories like suppressors and cleaning rods. Even rifles with mounted scopes find a secure and easy fit.
