Users of the CZ Supreme Field 20G in Grade III Walnut consistently comment on the wood quality and the fit-and-finish of the nickel chrome receiver. For an over/under in this price range, the engraving and stock figuring get genuine positive attention rather than generic praise.

On-range performance is described as smooth and reliable for both upland hunting and clay sports. The 20-gauge chambering keeps weight manageable for an all-day carry. Some users mention the price and note that comparable Italian guns cost more, while others would prefer an adjustable comb for competition use. The recoil is generally found comfortable given the gauge and gun weight. Overall sentiment is positive.
