The Retay ACE-R is an Inertia Plus recoil-operated semi-auto 12 gauge shotgun (Retay part no. RACEMX728) built for waterfowlers who want magnum-load reliability without the maintenance headaches of a gas gun. Its 3.5-inch chamber cycles everything from light target loads to full magnum shells, and the 28-inch barrel with an optimized, lengthened forcing cone tightens patterns for longer shots over decoys. A reversible safety and a removable, push-button trigger group make the ACE-R equally at home for right- or left-handed shooters and easy to clean in the field, while an Airy Pad recoil pad keeps felt recoil manageable on heavy loads. The stock wears a Realtree Max-7 camouflage finish and includes a shim kit to dial in a 14.5-inch length of pull for a precise fit. Backed by Retay USA and a limited lifetime warranty, it’s built to last for seasons of hard hunting.
