What makes the 300 AAC Blackout box special


Caliber-specific fit
Slots designed according to CIP dimensions give each cartridge firm, defined hold – play and rattling are minimized. Constructed according to CIP standard dimensions for 300 AAC Blackout.


Hinge lid with latch lock
The lid is hinged at the back and folds fully backward – the cartridges then stand upright and ready to grab in the securely fitting insert. A latch lock at the front keeps the lid securely closed during transport; to open, simply release the catch.


Stable & durable
Thick walls, densely printed layers – the box holds reliably together in the gun cabinet, range bag, and on the go. Reusable, no disposable carton.


Caliber marking in multicolor print
The caliber designation is multicolored directly integrated into the box print – permanent, without stickers and without engraving. In a full gun cabinet, you immediately grab the right box.



For sport shooters, hunters, and reloaders


Reloaders: one box per load (powder type, charge, bullet) – batch cleanly separated and clearly marked in multicolor instead of mixed loads.

Sport shooter: one box per discipline or firearm – defined quantity per box, ammunition count at a glance.

Organized stock: uniformly labeled in the gun cabinet, ready to grab for range, hunting ground, and range bag.


Made in Westerwald

From Westerwald, not from a container: We produce each box ourselves in 3D printing – largely with solar power from our own 22-kWp photovoltaic system. Material: Filamelt PLA+ 2.0.


Frequently asked questions about the 300 AAC Blackout box


Do my reloads fit too?
The box is designed for CIP-compliant cartridges. Own loadings with longer overall length (long bullets, shallow seating depth) can be tight near the upper OAL limit – if in doubt, ask briefly in advance.


Does the lid pop open in the backpack?
No. A latch lock at the front keeps the hinge lid securely closed so it does not accidentally open during transport. To open, release the catch with your finger; the lid then folds backward. Slight manufacturing tolerances are possible.


Are the boxes suitable for transport?
They are well suited for transport in the range bag – as an organizing and storage box. They do not replace a legally required safety container (WaffG/AWaffV) and are not hazardous material packaging.


Can the box withstand heat (e.g. summer trunk)?
Yes, it remains dimensionally stable under normal storage. High continuous heat – like in a hot trunk in midsummer – is not suitable for PLA; the box is not intended for that.


What are the tolerances in 3D printing?
Slight tolerances are part of 3D printing. The pa
Cartridges still find a secure hold in the slot – a minimal play remains due to the design; pressure on the bullet nose is avoided as much as possible.



No more loose cartridges
Choose the right size for 300 AAC Blackout – from the handy range box to the storage format for the cabinet.
