How we catalog rifle actions

Specification groups

Compatibility

Action length, footprint, magazine cut, trigger interface, barrel thread, pre-fit support and bolt-face choices.

Operation

Bolt and port side, bolt lift, lug count, feed system, extractor, ejector and interchangeable components.

Construction

Receiver and bolt materials, finishes, weight, recoil lug, rail arrangement and inclination.

Purchasing

Product type, price, deposit, lead time, FFL requirement, warranty, availability state and U.S. evidence.

Inclusion rules

1. The exact model must expose Left Hand or left bolt in current manufacturer documentation.
2. A U.S. manufacturer order path or current U.S. dealer listing must establish market availability.
3. Made-to-order, deposit, backorder and live stock remain distinct. Every claim carries a review date.
4. Manufacturer terminology is preserved while normalized fields support useful comparison.
5. Missing specifications remain unknown; no compatibility is inferred from footprint alone.
