This Carina AG Pump Defense pairs a 3 in chamber with a 5+1 capacity, accommodating both 2-3/4 in and 3 in shells. The 18.5 in vent-rib barrel is threaded for choke tubes, and the included set covers Full, Modified, and Cylinder. A brass bead front sight provides a straightforward sight picture on the rib.
The shotgun is built on an aluminum-alloy receiver with a matte black finish. The receiver is marked "Carina" with AG/RIA logos, and the barrel is marked "AG Pump Defense 12GA." Import and proof markings include APINTL – Pahrump NV, Derya Arms – Turkey, and proof tested.
Ergonomics are addressed with a synthetic stock featuring an adjustable cheekpiece, a recoil pad, and front and rear sling loops. The textured synthetic forend offers a secure grip for confident cycling. Length of pull is 14.0 in, and overall length is approximately 40.2 in.
Controls are simple and familiar, with a cross-bolt safety located at the rear of the trigger guard. The shotgun wears a uniform matte black finish across the receiver, barrel, and furniture for a cohesive, duty-style look.
