Built for everyone moving firearms data.

Six industries. One source of truth.

Whether you sell guns, design games, equip soldiers, train shooters, manufacture parts, or report the news, GunSpec is the data layer you stop building yourself.

  1. Retail & e-commerce

    Auto-populate product pages with verified manufacturer specs. Power typeahead. Drop hand-built comparison tables. Your shoppers get the answer; you get the conversion.

  2. Defense & procurement

    Procurement-grade comparison sheets, equipment registries, loadout planning tools. One schema across every sidearm, rifle, and crew-served system you evaluate.

  3. Game studios

    Eight balanced stat axes per weapon, tuned for Unity, Unreal and Godot. Drag the JSON in, ship a balanced shooter, skip the spreadsheet tuning sessions.

  4. Manufacturers

    Publish your own catalog through one upload. Sit next to the competition in side-by-side comparisons. Your marketing team owns the spec sheet, not your engineers.

  5. Training & simulation

    Power VR ranges, certification syllabi, and academy classroom modules with consistent, citable data. Same firearm reads the same across every course you ship.

  6. Media & journalism

    Fact-check on deadline. Authoritative specs for newsroom verification, technical writing, and film production armorers. One source instead of fifteen open tabs.

Three windows into one dataset.

Every firearm. Every cartridge. Every maker. In one schema.

6,656+ firearms, 759+ manufacturers, 540+ cartridges. Measured, normalised, joined across every dimension. The only firearms dataset on the internet you can hit from an API.

  1. Search the catalog.

    Lookups that don't break.

    Type 'glok', get Glock. Type '9mm', get every chambered model. FTS5 with BM25 ranking, snippets, highlights. Out of the box, on every tier.

    Retail

  2. Compare any three. Or five.

    The spec sheet, on demand.

    Three firearms, one call. Every dimension lined up. Best caliber, lightest weight, highest capacity already marked. The diff your procurement team would otherwise build in Excel.

    Retail · Defense

  3. Drop into Unity, Unreal, Godot.

    The only balanced firearms dataset.

    Eight production-tuned axes per firearm: damage, accuracy, fire rate, range, mobility, recoil, reload, concealment. Nobody else publishes balanced stats. Nobody else publishes them for thousands of models.

What the API gives you

Barrels. Calibers. Actions. Materials. Capacity. Features.

Every firearm in the catalog ships with the same shape of data, measured, normalised and citable. The spine of what a single /firearms/{id} returns.

  1. Barrel

    Length, profile, twist rate.

    Barrel length in millimetres, profile, contour, twist rate and rifling pattern. Returned for every model, indexed for range queries.

  2. Caliber

    Cartridge, energy, velocity.

    SAAMI / CIP cartridge specs: case dimensions, max pressure, typical muzzle velocity and energy. Joined back to the firearms that chamber it.

  3. Action

    Striker, hammer, gas, bolt.

    Action type, firing mechanism, trigger style and firing modes. Normalised vocabulary so a striker-fired Glock and a hammer-fired Beretta compare cleanly.

  4. Material

    Frame, slide, barrel.

    Polymer, steel, aluminium alloy, nitride finish. Per component, not a single string. Searchable by composition.

  5. Capacity

    Magazines, rounds, formats.

    Standard capacity, magazine type (detachable box, tube, belt, drum) and rounds-per-mag. Per variant where it differs.

  6. Features

    Rails, safeties, optics.

    Accessory rails, safety mechanisms, optic cuts, backstraps, threaded barrels. The boolean grid for filter UIs and game stats.

The atlas, every feature.

Search by what is actually on the gun.

Every firearm in the catalog is tagged across hundreds of manufacturing features. M-Lok rails, billet receivers, ambidextrous controls, nickel-boron bolt carriers. Filter, group, and ship only the firearms that match what your customers ask for.

  1. Billet receiver

    Machined from solid aluminium billet. Tighter tolerances than forged.

  2. Free floating handguard

    Mounted at the receiver only. No barrel contact, no harmonic interference.

  3. M-Lok

    Modular slot system. Rails, lights, grips bolt on, no smith work.

  4. Ambi charging handle

    Pull from either side. Same draw for left-hand and right-hand shooters.

  5. Ambi safety

    Selector mirrored on both sides of the receiver. No re-train for lefties.

  6. Ambi magazine release

    Drop a magazine with either hand. Tactical reload, both sides.

  7. Dual drop bolt release

    Bolt releases from both sides. Faster recovery after a reload.

  8. Mid-length gas

    Gas tube routed mid-barrel. Softer recoil than carbine length.

  9. Adjustable gas block

    Tunable flow. Match the load, suppress the rifle, dial out recoil.

  10. Nickel-boron BCG

    Ni-B coating. Self-lubricating, corrosion-resistant, brighter than nitride.

  11. Fixed stock

    Non-collapsing buttstock. Maximum cheek weld, simplest geometry.

  12. Muzzle brake

    Vented at the muzzle. Redirects gas, kills recoil, controls climb.
