What's Included
- Mossberg 500CG 20 gauge pump-action shotgun with 28 inch vent-rib barrel (fixed modified choke)
The 28 inch steel barrel uses a vent rib with longitudinal serrations and a matte top to reduce glare, paired with a single brass bead front sight. The fixed modified (M) choke delivers a practical constriction well-suited to a wide range of 20 gauge loads. Chambering accommodates both 2.75 and 3 inch shells for flexibility.
The action is the 500C-series pump with dual extractors and an anti-jam elevator, designed for consistent cycling and positive extraction. It uses a right-side ejection pattern with a bottom loading port and feeds from a 5-round tubular magazine.
The receiver is alloy with a black finish, matched to a blued barrel. Controls include Mossberg’s tang safety for intuitive operation. The stock is hardwood with checkering, a pistol-grip profile, and a ventilated recoil pad, and the length of pull measures 14.0 inches.
This shotgun follows the 500 series interchangeable barrel system via the magazine cap, adding configuration flexibility within the platform. It is a United States-made example from Mossberg’s North Haven, Connecticut facility, reflecting the straightforward, serviceable design the 500 series is known for.
