Detailed Features 

 
The 28" vent rib barrel gives a smooth swing plane for moving targets and aids heat dissipation during range sessions. Improved twin action bars prevent binding and twisting through the stroke, keeping cycling consistent. The drilled and tapped receiver accepts optics mounts. Three interchangeable flush Rem chokes (IC, M, F) let you tune the pattern for upland birds, waterfowl, or sporting clays without any additional purchase.

The 870 Fieldmaster in 20 GA with walnut and matte finish gets overwhelmingly positive reviews across the usual categories.

Reliability is the first thing most people mention. The 870 action has a long track record and this model continues that. The walnut and matte blued combination gets a lot of love for its traditional look; owners often note it feels and looks like a proper shotgun rather than a polymer-stocked utility gun. At 6.3 lbs the 20 GA version is noticeably lighter than the 12 GA models, which makes it a good recommendation for smaller-framed shooters or long days in the field.

Customization is another frequent topic. The 870 platform has broad aftermarket support, and owners enjoy swapping stocks, adding optics, or trying different choke configurations. Occasional customer service issues come up, typically tied to specific production runs, but they don't dominate the conversation.
