What’s Included
- Rock Island Armory M5 12 gauge pump-action shotgun
The 18.5 in barrel balances maneuverability with durability, using ordnance steel and capped by a simple front sight for straightforward indexing. The right-side ejection port supports reliable operation, and the 5+1 capacity offers a standard duty-ready loadout.
The matte nickel finish extends over the receiver and complements the factory ventilated metal heat shield, which helps protect the support hand and dissipate heat during extended strings. RIA branding appears on the receiver, with Rock Island Armory marked on the barrel.
The polymer stock includes an adjustable cheekpiece secured by a left-side clamping screw, allowing a tailored cheek height. A thick rubber recoil pad with a chevron traction pattern anchors the shoulder mount, while the fixed-stock layout keeps the handling consistent.
A ribbed polymer slide forend provides a positive grip surface. Sling attachment points are ready to use, with a front sling loop mounted to a separate barrel band just ahead of the magazine cap and a rear sling loop on the stock for straightforward carry setup.
Manufactured by Derya Arms in Turkey and imported by APINTL in Pahrump, NV, this M5 configuration aligns with Rock Island Armory’s AGM5 designation and presents a practical feature set in a compact, ready-to-use format.
