Patrol rifles

The same Mk1 platform we sell as our flagship, configured for duty use and delivered by the manufacturer. Three tiers, one receiver we machine ourselves, and one armorer who will still be answering the phone in three years.

Ambidextrous controls — a qualification issue

Standard · no upcharge

Off-hand qualification, weak-side shooting around cover and injured-officer procedures all assume an officer can run the rifle from either side. Every Ironcrest lower ships with an ambidextrous safety selector, bolt catch/release and magazine release as a specification — not an option package, and not a line item on your quote.

What this replaces

Most agencies either pay an aftermarket parts and labor bill per rifle to add these controls, or write off-hand manipulation out of their qualification course. Neither is necessary here.

Content slot — barrel, twist rate and weight values per tier to be confirmed from the current LEO catalog. Rows marked placeholder are not yet verified. Department-specific configuration (optic, light, sling, sight, magazine count) is quoted per agency.

Also available on a rifle order

Upper swap / refresh

Keep the serialized lower, replace the upper, and get a full inspection with the work. Quoted per rifle; volume scheduling available for a whole fleet.

Fleet standardization

One configuration, one parts bin, one armorer procedure across the department. We keep your configuration of record on file and build to it on re-order.

Serialization

Agency rifles serialize under the law-enforcement scheme, ICVALEO-XXXXX, engraved on the lower receiver. Serials are assigned by us and recorded in the A&D bound book — there is no prefix selection in a rifle order.
