Owners of the Vanguard Obsidian .243 Win tend to zero in on a few recurring points.

Accuracy gets consistent praise. The .243 WIN caliber is well-suited to both varmint and deer-sized game, and shooters commonly report tight groupings at range without needing to do much out of the box. Build quality also gets positive marks -- the materials and fit are generally described as solid for the price.
