Gear Guy — Real-Time 3D Firearm Configurator & Armory for iOS

01 3D Bench

Real 3D. Not a parts list.

Every part is a measured 3D model placed where it actually mounts. Swap a handguard and your light moves with it. Orbit, zoom, and inspect the configuration before you spend real money on it.

Parts list in, rifle out — then four saved builds off the bench. Captured from the app.

02 Compatibility Engine

It flags what doesn't fit. Live.

A red dot on a slide that was never cut for one. An RMR-footprint optic on an M&P that only takes it through an adapter plate, with no plate fitted. A SIG can on a muzzle with no Taper-Lok device, or on a barrel it isn’t rated for. Gear Guy checks fitment as you configure — optics-ready slides, footprints and plates, muzzle interfaces, bore ratings, rail space — and says what fixes it. It explains. It never lectures.

Compliance chips inform. They never block, and they never pretend to be legal advice.

Compatibility sheet on an M&P 2.0: the slide has no optic cut, and the RMR-footprint optic needs an adapter plate that is not installed — M&P 2.0 · no optic cut, no plate

Compatibility sheet on a P365: the Holosun 507K uses the Shield RMSc footprint and the base slide is not cut for optics — an optics-ready slide is required — P365 · needs the optics-ready slide

Compatibility sheet on a SIG MCX: a SIG can needs a Taper-Lok muzzle device, and the can is not rated for the barrel's caliber — MCX · wrong muzzle device, wrong bore

Compatibility sheet on a SIG MCX with no issues flagged and two suggestions: which MCX variants fit a mil-spec AR-15 lower, and setting the gas regulator when suppressed — MCX · a clear check, and which lowers fit

Swipe → four real sheets: three with the fix, one with nothing to fix.

03 Capability

What this build is actually for.

Gear Guy reads your configuration and tells you what it has fitted — a suppressor, a white light — and on rifle platforms, the engagement class the barrel and sighting system put you in. The figures are published doctrine numbers, shown with their source and their definition. Nothing is invented, and where we do not have a number we say so rather than estimating one.

Two capability sheets: an 18-inch DMR with a magnified scope reads a ~550 m class on the cartridge figure; a 14.5-inch carbine with a holographic sight and 3x magnifier reads ~300 m, limited by the sight

Same cartridge, two answers: the DMR is limited by the cartridge figure, the carbine by its sight. Both say which.

04 Randomizer

Role-based builds, one tap.

Tell it the job (CQB, home defense, DMR, retro clone), set a budget, and roll. The randomizer puts together a coherent build from real parts that fit together, priced and ready to inspect. Turn on Prefer parts I own and it fills every slot it can from your armory first, so the Parts-to-Buy sheet shows exactly what closes the gap — what to buy, what it costs, and the estimated total weight of the finished rifle. Keep rolling until something makes you stop.

The Randomize sheet: role chips, a budget range, Prefer parts I own switched on, and recent rolls — 1 · Role, budget, prefer what you own

A DMR roll on the bench: LPVO, bipod, suppressor-ready muzzle, five of sixteen parts already owned — 2 · A DMR roll, 5 of 16 parts already yours

Parts to Buy: 5 owned, 11 to buy, $7,649 to complete, full build value $8,842, estimated total weight 95.7 oz — 3 · What closes the gap, and what it weighs

A GWOT Clone roll on the Gear Guy bench: carry-handle ACOG, KAC RAS, vertical grip and a can — 4 · “GWOT Clone”, a retro roll

Swipe → one roll, from the sheet to the shopping list.

05 Exploded View

Every part. Labeled and priced.

Pull the build apart in 3D. Every component separates and carries its real product name; tap Labels and it shows what each one costs. Receiver sets that belong together say so when you pair them. The blueprint of the rifle you are planning.

Ten seconds of a DMR coming apart. Captured from the app.

Swap a KAC upper in and the bench tells you the matched lower paired with it.

06 Attachments

Dots, lights, cans. Placed, not dragged.

Optics seat in the slide cut. Lights ride the frame rail. Suppressors thread on the muzzle. The M&P9 M2.0 takes a Trijicon RMRcc and a SureFire XVL2, the P365-XMACRO its Holosun 507K, the SIG MCX a SIG SRD over its Taper-Lok brake, and the AR-15 carries the full catalog of lasers, lights, cans and glass. Every seat comes from measured geometry.

What is on the model shows as equipped. What does not fit says why.

07 Identify

Photo in. Armory record out.

Point it at something you own. Gear Guy identifies the platform, the parts it can see, and what they are worth, then files the whole thing into your armory as a structured record you can put on the bench in 3D.

Corrections are one tap. What it cannot verify, it says so. And anything it cannot name, you can: a custom part takes any brand and any model, so nothing you own goes uncatalogued.

An Armory record: the owner's photo of a SIG MCX on a wood floor, identified as a SIG MCX short-barrel configuration — 1 · Photo in, identity out

The same record's parts list: suppressor, handguard, grip, sling, magnifier, red dot and brace, priced, with one part marked unidentified — 2 · Parts, priced — one honestly unidentified

The same record's Show on Bench button and range log with lifetime rounds — 3 · On the bench, with its round count

Swipe → a real rifle, one photo, three screens.

08 Curious

Saw something at the range?

Think Shazam, for firearms. A rifle in a post you scrolled past, one across the counter, one on a table at a show — give Gear Guy the photo and it works out what it is looking at, part by part, and stands it up on the bench in 3D so you can turn it around and take it apart. It is a best guess and it tells you so; you correct whatever it got wrong, one tap at a time.

The result lands as a theoretical build: something to study, price out, and steal ideas from. It never enters your armory as something you own.

Just Curious result: a hand-held SIG MCX-SPEAR LT in Coyote identified at medium confidence, with the detected features listed

Spotted while scrolling — a Spear LT, part by part, at medium confidence. It says so.

From the result to the bench, tagged Spotted.

09 Range Log

Your rounds. Your ammo. Your targets.

Log a session against the firearms you shot. Gear Guy offers to deduct those rounds from the ammo you actually own, and puts them back if you delete the session. Attach photos of your groups. Every firearm record carries a lifetime round count, including the rounds it had before you started logging.

Encrypted with everything else. No timers, no coaching. Your records, not your training.

Logging a range session: date, location, notes, a rifle with 140 rounds of 5.56, and a note that 2,247 rounds are on hand in two lots — 1 · Log the session

The deduction sheet: 140 of 140 rounds from a 1,747-round lot of 55-grain 5.56, Deduct & Save or Don't Deduct — 2 · Deduct from a lot, or don’t

The saved session with a grouping photo and the line: deducted 140 rounds from inventory at save — 3 · Saved, with the target

Swipe → one real session, start to finish.

10 Armory & Vault

Private by construction.

Your collection lives in an AES-256-GCM encrypted vault on your phone. No account. No cloud copy of your armory. The only things that ever leave the device are a photo you choose to identify (downscaled, not stored) and a build you choose to share. The serial numbers you enter are masked by default and never transmitted — not to us, not to anyone. The armory is yours in the oldest sense of the word.

Saved builds, owned parts, values, and an insurance-ready export when you need it. Share a build as a link and it opens back into the app — the parts, not your data.

The Armory's Parts tab: 17 firearms, 161 parts, rounds and gear counted, an estimated collection value, and an Export inventory report button

A real armory. It stays encrypted on the phone it lives on.

11 Gear Locker

Your kit on a wall, not in a list.

Photograph a plate carrier, a helmet, a holster — Gear Guy lifts each one off its background and pins it to a board you arrange yourself. Group a carrier, its plates, the pouches and the medical kit into a named loadout and see the whole thing at once, the way it actually hangs in the closet. Plates to pouches, encrypted on your device like everything else.

The wall, captured from the app.

The Gear Locker filtered to a Hunting loadout: binoculars, a hoodie, a pen, a field notebook, a compass, a multitool, a pack, a reservoir and socks

A named loadout, filtered in one tap.

Platforms

Fifteen platforms in the configurator.

The AR-15 carries the full 3D parts bench — 251 parts and ten barrel lengths from 7.5″ to 20″. Thirteen of the fifteen render in 3D; the AK platform and Remington 870 are selectable with structured build records.
