How is gun case capacity calculated?

A: Register count plus twenty percent for new equipment, repairs and hand clearance.

Why size layers to the longest rifle?

A: A short layer forces a diagonal that occupies two slots; measure the longest weapon including optics.

Do locks need records?

A: Yes: tiered keys without records only narrow the group, with no trace of who opened when.

Must a gun case be fixed?

A: A loaded unit can tip; anchor into concrete or fit an anti-tip bracket with ballast.

What does acceptance involve?

A: Open fully loaded, measure the gap, check shelf deflection, walk the key tiers. ---

Choosing a Gun Case: Capacity, Layering and Access Control

Quick answer: Select a gun case by capacity, layering and access control, and only then by doors. Capacity follows the register plus twenty percent, layering follows rifle types and lengths, and access control follows who opens it and whether that is recorded.

FAQ

1. Three priorities in order

Capacity is the visible figure and the easiest to over-weight. Register count plus twenty percent beats sizing for a theoretical maximum, which leaves the cabinet half empty and squeezes out new arrivals.

Layering sets access and counting speed: long guns, short guns and accessories in separate zones, so a count finishes inside each zone instead of emptying the cabinet.

Access control decides whether management works. Single, three-point and tiered keys map to three levels of control; a tiered system without handover rules only adds opening time.

Item	How to size	Typical	If wrong
Capacity	register plus 20 percent	10 to 30 pieces	half empty or short
Layering	long, short, accessories	three zones	counting empties the cabinet
Access control	by handover rules	three-point with key tiers	no traceability
Fixing	by floor	anchors plus anti-tip	shifts when knocked

2. Capacity and layering: why twenty percent

The twenty percent covers new equipment, a rifle in for repair, and hand clearance. The third is forgotten: a packed cabinet means moving neighbours to take one out, sometimes doubling the time.

Layer height follows the longest rifle, not the average. Short height forces a diagonal, which occupies two slots and reduces capacity. Measure the longest weapon including optics and take the larger figure.

Short guns and accessories can share a zone but need a physical divider; mixed together, accessories sit on guns and must be moved first.

3. Access control: three forms, three levels

A single lock suits a fixed crew locking at night. Three-point suits pry resistance without key tiers, with bolts entering three positions. Tiered keys suit handover: manager, supervisor, duty officer.

Control needs a record. Paper or electronic, the form matters less than answering who opened it and when; tiered keys without records only reduce the number of people who can open it.

Check the door gap too: beyond three millimetres a pry bar fits, too tight and a damp body will not close. One to two millimetres, measured with feeler gauges.

4. Fixing and anti-tip

A loaded cabinet concentrates weight at the butt end. Standing on its own, it can tip when knocked or when a door is swung hard. Fix by floor: anchors in concrete, load plates on raised floors, an anti-tip bracket and ballast in temporary stores.

One cheap measure: put the heaviest weapons low or nearest the hinge. It costs nothing but requires the internal layout to be planned at purchase, or weight follows convenience.

5. Acceptance and common mismatches

Four actions: open fully with the cabinet loaded and watch for tipping, measure the door gap, check shelf deflection layer by layer, and walk the key tiers once. Fifteen minutes covers structure, sealing, load and control.

Mismatches cluster in two places: sizing for a theoretical maximum leaves it half empty, and buying locks on price leaves rules without records — the second costs an extra check at every handover.

Conclusion

Three steps: capacity from the register plus twenty percent, layer height from the longest rifle across three zones, and access control from the handover rules. Doors come last; start with doors or price and one item gets bought twice.
