Overview

Built for hunters who need a dependable semi-auto in changing conditions, this shotgun is set up for waterfowl and upland work with a 28" barrel and 3.5" chamber for heavy-hitting loads. The Active Valve gas system is designed for smooth cycling across a range of loads, while the Inflex recoil pad helps reduce felt recoil during long days in the field. A Realtree Max 7 synthetic stock, Cerakote Flat Dark Earth finish, and sling swivel studs round out a practical package for carrying and hunting in harsh environments. It also includes three Invector-Plus choke tubes—Full, Modified, and IC—so you can tailor the setup to the hunt.

Considerations & Trade-offs

  • The 28" barrel and 3.5" chamber make this a more specialized setup, so it may feel less compact than shorter-barreled options for hunters who prioritize tight handling.
  • The 4+1 round capacity is practical for hunting use, but it is not intended for high-volume shooting without reloading.
  • The included choke set covers common hunting needs, but users who want a different patterning setup will need to add other Invector-Plus choke tubes separately.
  • The Realtree Max 7 synthetic stock and Cerakote Flat Dark Earth finish are built for field use, but the overall look is purpose-driven rather than understated.
