Owners of the Rob Roberts A300 Ultima Exclusive in Bayou Deview are almost exclusively waterfowl hunters who want a field-tuned shotgun with a purpose-built finish. The Bayou Deview pattern draws consistent praise for matching marsh and flooded timber environments, and the duck cocking handle is frequently mentioned as a genuine field improvement.

The Flat Dark Earth receiver pairs well with the Bayou Deview furniture in most owner photos, and the Tan rib barrel completes the low-visibility look. Some buyers feel the finish combination adds meaningful value over a stock A300. Others see it as cosmetic and debate whether the premium is warranted.

The underlying A300 platform is trusted for reliable cycling across a range of 12 Gauge loads. Trigger feel is consistent with the base Beretta A300 and is generally accepted as adequate rather than refined. The 28-inch barrel is considered a good all-around length for typical waterfowl work.
