Stripped lower
An Ironcrest-manufactured AR-15 lower receiver, machined, serialized and engraved here, logged in our A&D bound book, and transferred to you on a Form 4473 at your appointment. Build whatever you want on top of it.
Material — variant
Prefix is selected from this list only — never typed. Five sequential digits are assigned by us, not chosen. NFA-scoped prefixes (ICBOOM) and law enforcement prefixes (ICVALEO, ICHUSH) are not available on a civilian stripped-lower order.

Prefix policy
A custom prefix is scoped to standalone stripped-lower orders. Complete rifles — Sentinel, Redline, civilian or law enforcement — always serialize under the standard scheme, and no prefix selector appears in those flows.
Every serial is unique across our whole manufacturing history: house prefix, hyphen, five sequential digits, no exceptions.
Building on it
