The Mossberg 600AT is a practical, no-frills pump shotgun for shooters who want a U.S.-made 12-gauge workhorse with adaptable pattern control. It’s best suited for collectors, budget-minded home defenders, or range users who understand that a serviceable firearm can be improved with routine maintenance and targeted upgrades.

MOSSBERG New Haven 600AT

Key features and what they mean for use

The MOSSBERG New Haven 600AT is chambered for 2 3/4″ and 3″ 12ga shells, giving flexibility between lighter target loads and heavier defensive or hunting rounds. The pump action platform is dependable and easy to maintain, and the inclusion of a C-Lect-Choke at the muzzle provides on-the-fly pattern adjustment—useful for switching from tighter, longer-range shot patterns to more open patterns for close targets.

Action, choke, and pattern control

The C-Lect-Choke is a notable feature on this example. As an adjustable muzzle device it allows the shooter to tailor shot spread without swapping tubes, which is a practical advantage in the field or on the range. Combined with the shotgun’s ability to run both 2 3/4″ and 3″ 12ga shells, you get a versatile platform for multiple roles.

Condition notes and recommended maintenance

This unit was made in the U.S.A. and shows honest wear: the stock has several scratches and the finish near the butt plate appears to have sustained water damage. The receiver is etched with the name “Paul Sirlet” and his driver license number, and the barrel and magazine tube show light surface rust. These are repairable issues—surface rust can be cleaned and blued touch-up or honest refinishing can restore appearance and function. Be aware the etched receiver is a permanent cosmetic condition.
