US 12,753,984 B2 · Firearm and extractor, bolt and trigger pin assembly

Abstract

A cartridge extractor for positioning about a portion of a firearm bolt includes an outer curved surface that defines an outer perimeter of the annular body, an inner curved surface that defines an inner perimeter of the annular body, a first axial face extending between the outer curved surface and the inner curved surface, and a second axial face extending between the outer curved surface and the inner curved surface and spaced apart from the first face in an axial direction. An extractor arm extends axially from the first axial face and has an engager end distal from the annular body and a cartridge engager flange at the engager end of the extractor arm. Also disclosed are a pin assembly for securing a trigger to a receiver, an adjustable bolt handle which when locked can transfer very high loads, and a firearm.
