Description
Retay built the ACE to compete with inertia guns costing a good bit more, and the Extra Black version is the workhorse of the lineup. At the heart of it is the Inertia Plus system, a rotating bolt design with a torsion spring that keeps the bolt locked into the chamber until it is supposed to open. No gas ports, no pistons gumming up with carbon, just a clean-running action that keeps cycling in cold blinds, wet fields, and dusty clays courses. With a 3.5 inch chamber and 3+1 capacity, it will digest light 2.75 inch target loads one weekend and heavy waterfowl magnums the next.
What Sets the ACE Extra Black Apart
The 28 inch barrel is deep bore drilled for straightness and topped with a vent rib and a fiber optic front bead that picks up light fast on overcast mornings. Retay lengthens the forcing cone at the factory, which smooths out patterns and takes a little sting out of stout loads. Speaking of recoil, the Airy Pad is one of the better factory pads out there, with a cushioned design Retay says cuts felt recoil by up to 30 percent. Pair that with the included shim kit for adjusting cast and drop, and you can get this gun fitted to your build instead of fighting a stock that does not point where you look.
Thoughtful Touches on the Retay ACE
The oversized safety button is reversible for left-handed use, the trigger group pops out at the push of a button for easy cleaning, and the steel receiver comes drilled and tapped if you want to add an optic for turkey season. The ACE also accepts Benelli Crio Plus pattern chokes, so aftermarket tube options are wide open beyond the MaraPro set that ships in the box. At around 7.25 pounds it carries comfortably on long walks, and the matte black synthetic furniture shrugs off weather and briars. Retay backs it with a limited lifetime warranty, which says a lot about how much faith they have in this action.

Frequently Asked Questions
Will the Retay ACE cycle light target loads reliably?
Yes, that is one of the strong points of the Inertia Plus system. The ACE is designed to run everything from light 2.75 inch target loads up to heavy 3.5 inch magnums without adjustment. Like most inertia guns, a short break-in period with mid-power loads helps everything settle in, but owners consistently report smooth cycling across a wide range of shells.
What choke tubes fit the Retay ACE Extra Black?
It ships with a set of MaraPro flush-mount chokes covering Cylinder through Full. The ACE series also accepts Benelli Crio Plus pattern chokes, so you have plenty of aftermarket options from makers like Briley, Carlson's, and Trulock. Just make sure any tube you buy is listed for Retay or Crio Plus threading.
Can I mount an optic on this shotgun?
You can. The steel receiver comes drilled and tapped from the factory, so adding a rail or red dot mount for turkey hunting or slug work is straightforward. For wingshooting, the vent rib and fiber optic bead work great as-is.
How is the ACE different from the Retay ACE-R?
The two share the same internals and Inertia Plus operating system. The main difference is receiver shape: the standard ACE has a classic slope-back profile while the ACE-R uses a slight humpback design that some folks prefer for its sight plane. Choosing between them mostly comes down to which look and feel you like better.
