Primos Jellyhead Max Mbrg 12ga .690

The Primos Jellyhead Max Mbrg 12ga .690 is a precision-engineered shotgun choke tube designed for Mossberg 12-gauge shotguns, delivering consistent pattern density and predictable shot placement across hunting and sport shooting applications. The .690-inch constriction diameter positions this choke in the modified range, balancing effective range with pattern control for waterfowl, upland game, and clay target sports.

Primos choke tubes are manufactured to tight tolerances that ensure reliable cycling and repeatability from shot to shot. The .690 constriction specification is engineered to hold patterns tight enough for 40-yard effective range on waterfowl while remaining open enough for hunting situations where fast target acquisition matters. This middle-ground constriction works effectively with standard and steel shot loads in modern Mossberg 500 and 835 platforms, making it a versatile tube for hunters who don't want to swap tubes between different game species or shooting scenarios.

The Jellyhead Max series is built for shooters who demand consistent performance across varying shot types and distances. Field hunters appreciate the ability to move between modified and full chokes without purchasing separate shotgun barrels—a simple tube swap takes seconds and costs a fraction of barrel replacement. Sport shooters running clay courses value the predictability that precision constriction brings to score-building.

Mossberg compatibility means this tube fits M500, M535, and M835 models directly, with the Mbrg designation confirming interchangeability across Mossberg's Accu-Set choke system platform. For hunters already invested in Mossberg shotguns, the Jellyhead Max .690 offers a cost-effective way to fine-tune shot patterns without upgrading to different shotgun hardware.
