We machine the receiver your rifle is built on
Every Ironcrest lower is cut, serialized and engraved on our own CNC and fiber-laser equipment, recorded in our A&D bound book, and assembled here. We are a manufacturer with a shop — not a retail counter with a logo.
Ambidextrous as standard
No upcharge · every tier · every lineEvery Ironcrest-manufactured lower — Sentinel, Redline, civilian, law enforcement or dealer — ships with an ambidextrous safety selector, bolt catch/release and magazine release. It is a specification, not an option package. Most builders charge $200 or more for the same parts, or do not offer them at all.
Left-handed shooters, off-hand qualification and injured-hand manipulation are not edge cases. Building one lower configuration means one parts bin, one assembly procedure, and no upcharge to pass along.
| Control | Specification | All tiers |
|---|---|---|
| Safety selector | Ambidextrous, 45°/90° throw | Standard |
| Bolt catch / release | Ambidextrous, left-side paddle | Standard |
| Magazine release | Ambidextrous, both sides | Standard |
| Upcharge | None on any line or tier | $0 |

- 01Pick or configure
Choose a tier on a product page or spec a build in the configurator. Ambidextrous controls are already in the price.
- 02Order online
Civilian orders check out through our commerce backend. Nothing about the transfer happens in checkout.
- 03We build and serialize
Your lower is machined, engraved and logged in the A&D bound book under the standard ICA-XXXXX scheme.
- 04Appointment and transfer
You come to the shop by appointment for the Form 4473 and pickup. NFA items wait on ATF approval first.
Transfer paperwork, FFL selection and the Form 4473 happen at your scheduled appointment in our facility — never in the online checkout. Drop-off only; we do not accept shipped unserialized firearms.
Agency procurement and service contracts
Patrol rifles, Form 5 suppressors, armorer contracts, Glock optic cuts and Certificates of Destruction — with written inspection reports and a 24-hour on-call acknowledgment. Departments start with a complimentary on-site patrol rifle inspection.
Come see the shop floor
Consultations, drop-offs, pickups and transfers are scheduled. We operate out of an I-1 light-industrial facility and are not a walk-in retail shop.
