Description
The Retay ACE-R Bronze Mossy Oak Bottomland is a 20-gauge semi-automatic shotgun built for hunters who want premium performance without the sticker shock that usually comes with it. Chambered for 3-inch shells and running on Retay's patented Inertia Plus action, this gun cycles reliably from light upland loads to heavier field shells without skipping a beat. The 28-inch deep-bore drilled barrel gives you a smooth, consistent swing, and with an overall length of 50 inches and a weight of just 6 lbs. 6 oz., it carries easy and comes to your shoulder fast. The Bronze Mossy Oak Bottomland finish gives it a sharp look in the field while still being practical camo.
What Makes the Retay ACE-R Inertia System Worth Knowing About
A lot of inertia shotguns have one quiet weakness: the bolt can get jarred out of battery in rough terrain or during fast follow-up shots, and that costs you birds. Retay addresses that directly with their Inertia Plus bolt, which uses a rollover torsion spring to lock the bolt head into battery under any conditions. The result is quiet bolt closure, virtually zero bolt rattle, and a gun that goes bang when you pull the trigger. The factory-lengthened forcing cone and deep-bore drilled barrel work together to keep your pattern tighter and more consistent shot to shot.
Retay ACE-R Features That Actually Matter in the Field
The ACE-R's push-button removable trigger group is one of those features you don't appreciate until you've cleaned a muddy inertia gun the hard way. Drop the trigger group out at the press of a button, give everything a quick wipe-down, and you're back in business without tools. The AIRY recoil pad, which uses an internal air pocket design, cuts felt recoil by up to 30% compared to a standard pad. That matters a lot in a lighter 20-gauge that you're shooting all day. The oversized, reversible safety is ambidextrous-friendly, and the single fiber optic bead up front makes target acquisition quick in low-light conditions. It ships with an impressive choke tube set: Cylinder, Improved Cylinder, Modified, Improved Modified, Full, and Waterfowl Extended Long Range. Length of pull is 14.5 inches including the shim kit, so fit adjustability is built right in. Retay backs this gun with a Limited Lifetime Warranty, which says a lot about how they stand behind their product.

Frequently Asked Questions
What choke tubes come with the Retay ACE-R 20 gauge?
The ACE-R ships with six choke tubes: Cylinder, Improved Cylinder, Modified, Improved Modified, Full, and a Waterfowl Extended Long Range tube. That's a solid selection that covers everything from close-flushing upland birds to decoying ducks. The threading is standard, so aftermarket options are widely available if you want to expand further.
How light is the Retay ACE-R in 20 gauge, and is it balanced well?
It comes in at 6 lbs. 6 oz., which is genuinely light for a full-featured semi-auto. The 28-inch barrel helps keep the balance point out front, which makes for a smooth, natural swing on moving targets. Most hunters find this weight sweet spot makes it comfortable for long days in the field without feeling wispy or hard to control.
What is the Inertia Plus system on the ACE-R, and how is it different from a standard inertia action?
Standard inertia actions use a spring to cycle the bolt, but they can occasionally get jarred out of battery during rough handling, costing you a shot at the worst possible moment. Retay's Inertia Plus adds a rollover torsion spring inside the bolt that actively rotates the bolt head into a locked position and holds it there. This virtually eliminates out-of-battery misfires, reduces bolt rattle, and allows for quiet bolt closure. It's a real improvement on the classic Bruno Civolani design that inertia guns have been based on for decades.
Can the trigger be removed without tools on the Retay ACE-R?
Yes, and it's one of the nicest features on this gun for anyone who hunts in tough conditions. A single push of a button drops the entire trigger group out of the receiver, no tools needed. That makes field cleaning genuinely quick and straightforward. It also means you can store the trigger group separately, which disables the firearm entirely.
Is the Retay ACE-R a good fit for a smaller-framed shooter or someone new to semi-auto shotguns?
The 20-gauge configuration and light weight make it a great option for smaller-framed or newer hunters who want to avoid the heavier recoil of a 12-gauge. The AIRY recoil pad reduces felt recoil by up to 30% compared to a standard pad, and the shim kit allows you to fine-tune the length of pull for a better fit. The oversized, reversible safety also makes it easy to operate for both right- and left-handed users.
What kind of loads will the Retay ACE-R 20 gauge cycle reliably?
The ACE-R is designed to handle a wide range of 20-gauge 3-inch shells, from lighter upland target loads to heavier hunting loads. The Inertia Plus system is engineered for consistent cycling across that load spectrum. As with any inertia shotgun, very light practice loads near the minimum threshold can sometimes cause short-cycling, so it's worth testing your preferred loads during a range session before heading to the field.
