What’s Included
- New Haven by Mossberg 600CT 20 Gauge pump-action shotgun
The 600CT denotes the 20-gauge variant within the New Haven 600 line, a private-label counterpart to the Mossberg 500. It is marked Made in U.S.A. and retains broad parts and barrel interchangeability with the Mossberg 500 platform.
The 28 in steel barrel features a vent rib and a fixed Modified choke for versatile patterns. It is chambered for both 2 3/4 in and 3 in shells, and the single brass front bead provides a clear, simple sight picture. This listing explicitly includes a 3 in chamber and Modified choke.
An anodized aluminum alloy receiver keeps weight down and uses right-side ejection. The 600 models are documented as omitting receiver drilling/tapping and including a magazine anti-rattle feature. The tubular magazine is configured 2+1.
Controls and furniture are straightforward and familiar: a tang-mounted sliding safety, wood stock and slide-handle with impressed checkering, and a 14.0 in length of pull. The metal wears a blued finish, complementing the classic wood furniture.
