Definition

A bolt-action sniper rifle favored by U.S. Navy SEALs and other military sharpshooters who need to reach out and touch someone from very, very far away. This .308 Winchester chambered weapon is the professional's choice for long-range precision work, often confused with civilian hunting rifles by people who get their gun knowledge from video games. It's what you use when "spray and pray" isn't in your vocabulary.

Example Usage

The sniper team set up position with their M40A1, maintaining overwatch on the compound from 600 meters out.
