Owners of the Charles Daly 520 side-by-side tend to appreciate its classic double-gun layout in the lighter 20-gauge platform. The wood stock and overall aesthetic draw in buyers who want a traditional field look without a premium price tag. First impressions of fit and finish are generally positive for the price point.

The single selective trigger gets mixed reviews. Some find it intuitive and clean; others would prefer a traditional double trigger arrangement for more deliberate barrel selection in the field. The 26-inch barrel length suits upland hunting well.
