R.U.M. / The Craft

Coat. Engrave. Armorer. Build.

We change and make guns: finish them, mark them, take them NFA, and build them from the ground up. Every job is scoped and quoted up front, and every transfer goes by the book.

01 · COAT

Cerakote

Walk-in booth · two cure ovens · in-house blast

Ceramic coating that outlasts the gun. We strip, degrease and blast to bare, coat in a full walk-in booth, and oven-cure every part. Prep is the job; the color is the reward.

Laser engraving

Fiber laser · rotary for round parts

Logos, dedications, artwork and "X of N" serialization, cut clean and permanent on bare metal, anodized aluminum or fresh Cerakote. Two-tone work laid through the coating is where the laser and the booth meet.

NFA work

Licensed manufacturer · Class 2 SOT

The work most benches legally can't touch. As a licensed manufacturer with a Class 2 SOT, we handle NFA marking, short-barrel builds and suppressor-ready setups, and we walk you through the paperwork so it's done right the first time.

Send-in service

How a job runs

Same four steps whether it's a slide or a full build.

Tell us

Send the request below with the gun's make and model and what you're after. We come back with scope, finish options and a price.

Bring it or ship it

Drop it off in Arnold, or ship it in. We send exact packing and shipping instructions before anything moves.

The work

Logged in, photographed, prepped, finished or built, and checked before it leaves the bench.

Back to you

Picked up or shipped back the compliant way. New builds and drops go out through a 4473 and background check.

Straight answers

Questions

What does it cost?

Every job is quoted up front, after we know the parts and the pattern. Send the request below and you'll have a number before anything ships.

Can I buy a rifle online?

Not with an add-to-cart. Builds and drops are reserved here, then transferred in person at our counter or shipped to your local FFL, with a 4473 and background check either way.

Can I ship you my gun for a finish?

Usually, yes. Ask first: we'll confirm the job and send the exact way to pack and ship it so it arrives, and comes back, by the book.

Do you do repairs?

That's not our lane. We change and make guns: finish, engrave, NFA work and builds. For repairs, bluing and hand-fitting we'll point you to a bench we trust.

How do drops work?

Join the Crew on the home page. Members hear first, seats are a free draw, a deposit holds your number, and the rifle transfers by the book. When a run sells out, that finish is retired.

Where are you?

Arnold, Missouri. Hours and the shop address are coming with the opening; send a request and we'll set a time.
