From publisher blurb:
Looking for a sniper rifle? Well look no further!
This volume focuses on 43 Sniper Rifles that are currently in use by Police and Armed Forces around the world. Each rifle is seperately detailed with its own pictures, description, and technical details. It also features the Sniper prestige class and a glossary of gun terms.
Although this product provides game statistics for d20 Modern, the technical details provided mean that it can easily be used for other systems.
