Detailed Features 

The Inertia Plus bolt system cycles reliably across a wide range of loads, which matters when running both light target loads and magnum hunting shells out of the same gun. Five MaraPro chokes included: F, IM, M, IC, S. The Quick Unload System lets you clear the chamber without firing. Oversized SP controls work with gloves on — a practical feature for waterfowl and cold-weather hunting. 
 

Usage 

The 3.5-inch chamber and 28-inch barrel combination suits waterfowl hunters who need magnum loads and a longer sight radius. Also works for upland birds and clay sports.

Build quality and the gray Cerakote finish get consistent positive comments. The matte black barrel paired with the gray receiver is a popular look. Cycling reliability with a wide range of loads comes up often as a genuine strength — most owners report clean function across both light and heavy shells.

Recoil management is described as good for an inertia-driven 12 gauge. The 3.5-inch chamber capability is noted positively by waterfowl hunters who run magnum steel shot loads. A few owners mention the stock is slightly short for taller shooters, which is a common complaint with factory-length stocks.

Occasional compatibility issues with the lightest target loads appear in a handful of reports, typical for inertia designs that depend on shell energy to cycle. Aftermarket options are somewhat limited compared to more established platforms. Overall sentiment is positive — most buyers are satisfied with the gun's field performance.
