A biasing member for a bolt assembly of a firearm is described herein. The biasing member comprises a body having a first portion configured to engage and seat within a biasing member receiving indentation of an arm of the extractor, and a second portion configured to engage and seat within a receiving area along a bolt of the firearm. The body provides a biasing force directed against the extractor arm. The body comprises an elastomeric material, and is configured such that the first and second portions provide varying levels of compression sufficient to maintain a substantially constant extractor tension between the extractor arm and a cartridge. |
