Ammo boxes solve the one problem every workshop has: damp, dust, and small parts that go missing off the bench. Genuine ex-military tins, steel storage boxes, and wooden crates all turn up on workshop walls for a reason, and in 2026 the grading and price on each one varies enough to matter.
- Genuine US/Italian 50 cal ammo tin (£15) wins on seal quality for ammo boxes workshop storage - buy it.
- Laycorn steel storage box (£55) is the modular, stackable pick for a proper tool wall - buy.
- PA156 large mortar ammo box (£20) takes the oversized kit the tins can't fit - buy for bulky tools.
- Skip folding storage boxes for anything heavy; the hinge and latch aren't built for daily lifting.
Why this matters
A proper 50 cal ammo tin was built to survive being thrown around the back of a truck for years and still keep its contents bone dry. That's a higher bar than most plastic totes sold as "workshop storage" ever get tested against.
The trade-off is weight and cost against a plastic tote, and not every ammo box on the market is graded the same way. Some are genuine MOD or Warsaw Pact issue, some are brand new unissued stock, and some are reproductions dressed up as surplus. Grading matters more here than in most storage categories because a knackered seal on a steel tin defeats the entire point of buying one.
How this list is graded
Every item below gets judged on four things: build material, seal or closure quality, stackability on a shelf or bench, and price against what genuine surplus condition actually costs in 2026. Genuine MOD-marked stock gets weighed differently to reproduction or "military style" pieces, and that's flagged in every verdict.
Condition grading follows the same terms used across the surplus trade: Grade A means light service wear with no structural issues, Used means functional but with cosmetic damage, and New or NOS means unissued stock that never saw a depot. None of that grading is marketing - it's what you're actually paying for.
The ranked list
1. Genuine British Military "Laycorn" (Lacon) Steel Storage Box – Grade A
The heavy-duty pick. Side-opening steel construction with a modular, stackable design meant for depot storage, priced at £55 in 2026. This is genuine MOD issue, not a repro, and it's built to take the weight of a full set of hand tools without the lid bowing.
If you're building a wall of matching boxes rather than one-off storage, the modular stacking is the reason to pick this over a tin. Verdict: Buy if you want a proper steel unit that stacks square.
2. Genuine US/Italian 50 Cal Ammo Tin – Grade A
The classic. A 50 cal ammo tin at £15 in Grade A condition, near-mint, with a waterproof rubber seal still doing its job decades after leaving service. This is the size most people picture when they think ammo box, and it's the right size for fixings, small hand tools, and anything that hates damp.
At this price it's hard to beat for a single unit. Verdict: Buy, especially as a first tin to test the format.
3. Brand New 50 Cal Ammo Tin
Same size and shape as above, but unissued rather than graded surplus, also at £15. The genuine MOD-marked seal is fresh rather than decades old, which matters if you're storing anything moisture-sensitive like abrasives or electricals.
The price parity with the graded tin makes this the easy pick for anyone who wants no service wear at all. Verdict: Buy if unissued condition matters more than character.
4. PA156 Large Metal Mortar Ammo Box
The oversized option. Built to MILSPEC standards and originally sized for mortar rounds, this one runs £20 and swallows the long or bulky tools that won't fit a standard 50 cal tin - pry bars, extension leads, a full socket set still in its tray.
It's heavier to lift full than the smaller tins, so it works best sat on a low shelf rather than stacked high. Verdict: Buy for the awkward-sized kit everything else struggles with.
5. L17A1 Medium Calibre Ammo Box
A precision-built box to UK MOD Drawing No. SV575A, priced at £25, sitting between the 50 cal tin and the mortar box on size. This is the pick for someone who wants genuine MOD spec but doesn't need the largest footprint on the bench.
The build quality is consistent because it's manufactured to a fixed drawing spec rather than varying batch to batch. Verdict: Buy for a mid-size unit with no surprises.
6. AK101 M33 5.56 Polish Army Wooden Ammo Box
The wildcard. A genuine Polish Army wooden crate at £20, roughly 40cm wide by 15cm high with carry handles and a latch closure. It looks better on an open shelf than any of the steel options, and the timber construction means it won't dent tools the way steel edges can.
Wood doesn't seal against damp the way a rubber-gasket tin does, so this isn't the pick for a leaky outbuilding. Verdict: Consider for a dry workshop where looks matter as much as function.
7. Military Style Folding Storage Box
The budget flat-pack. At £14 this folds flat for storage when empty and locks with a simple side mechanism when built. It's the lightest option here and the only one not built to genuine military spec.
Fine for light odds and ends, but the folding hinge isn't rated for the daily lifting a steel tin or box takes without complaint. Verdict: Skip for anything heavier than fixings and small parts.

Where to buy
- Check the grading term on the listing before you buy: Grade A, Used, or New/NOS all mean different things and price accordingly.
- Confirm the seal is described as intact, not just the box - a dented steel tin with a perished gasket is no better than an open shelf.
- For a deeper look at pairing these boxes with a full tool setup, the dedicated tool storage guide covers stacking layouts and shelf spacing in more detail.
FAQ
What's the best ammo box for workshop storage in 2026?
The Genuine US/Italian 50 Cal Ammo Tin at £15 is the best all-round pick for ammo boxes workshop storage in 2026 because of its waterproof rubber seal and low price. For bulkier tools, the PA156 Large Metal Mortar Ammo Box at £20 fits what the smaller tin can't.
Are genuine ammo tins better than plastic totes for tool storage?
Genuine ammo tins seal against damp far better than most plastic totes, thanks to the rubber gasket built into the original MOD design. They cost more upfront - £15 to £55 in this list - but they don't crack or warp the way plastic can over years in a cold outbuilding.
Is a wooden ammo box durable enough for tools?
A wooden ammo crate like the AK101 handles weight and knocks well because of its solid timber build, but it doesn't seal against damp the way a rubber-gasket steel tin does. It's a better fit for a dry workshop than a leaky shed.
How much does an ammo box cost for workshop storage?
Ammo boxes for workshop storage run from £14 for a basic folding box up to £55 for a genuine steel Laycorn storage box in 2026. Most genuine 50 cal tins and medium ammo boxes sit in the £15 to £25 range.
What does Grade A mean on an ammo box listing?
Grade A means the item has light service wear with no structural or seal issues, as opposed to Used stock which is functional but shows more cosmetic damage. It's a grading term used across the surplus trade, not a marketing label.
Can ammo boxes be stacked on shelving?
Steel boxes like the Laycorn storage box and the L17A1 are built to stack square on shelving without the lids bowing under weight. Wooden crates and folding boxes stack less reliably because they weren't designed for depot-style modular storage.
Do ammo boxes actually keep tools dry?
Genuine ammo tins with an intact rubber gasket seal keep moisture out well enough to have protected live rounds in the field for decades. That's the entire reason the design still gets reused for workshop, garden, and allotment storage in 2026.
One last thing
The rubber gasket seal on a genuine 50 cal tin isn't a bonus feature bolted on for the surplus market - it's why the tin still seals decades after leaving MOD service, long after any plastic tote from the same era has cracked and gone in the skip.
