What’s Included
- Mossberg 505 Bantam 20 Gauge pump-action shotgun with Mossberg pistol-grip stock
- Improved cylinder choke installed
The 505 Bantam receiver is unique to Mossberg’s youth line, scaled down from the Model 500 yet retaining twin action bars and an anti-jam elevator for smooth cycling.
This example features a Mossberg factory pistol-grip kit in place of the standard shoulder stock, giving shooters tight control in close quarters while remaining modular for future stock swaps.
The 20" carbon-steel barrel wears a vent rib with a white front bead and brass mid-bead, promoting quick sight alignment. It is threaded for Mossberg’s Accu-Choke system, and the sale includes an installed improved cylinder choke for versatile patterning.
Chambered for both 2 ¾" and 3" shells, the gun holds 4+1 rounds and relies on an ambidextrous top-tang safety—an uncommon feature among pump shotguns—allowing easy operation for right- and left-handed users.
A matte-black aluminum receiver keeps weight down, while the gold-plated trigger and EZ-Reach synthetic forend add signature Mossberg touches that make handling intuitive and comfortable.
