The Retay Ace in black is typically bought by shooters who want a plain-finish 3.5-inch semi-auto without camo. Waterfowl and turkey hunters who hunt in open areas where black is acceptable make up a large part of the buyer base, along with range shooters who prefer a traditional look.

Performance impressions mirror the rest of the Ace line. The 28-inch barrel and 3.5-inch chamber give owners flexibility with load selection, and the vent rib is consistently noted as useful for wingshooting. The same cycling sensitivity with light loads comes up in reviews, a pattern across all Ace variants that new owners should be aware of.

On pricing and finish, the black Ace tends to draw the most direct comparisons to domestic competitors. Many owners feel the Ace offers competitive value, though the trigger pull and the limited aftermarket both get mentioned as areas where more established platforms have an edge.
