The Remington 870 Fieldmaster Compact is a pump-action shotgun chambered in 20 gauge with a 3-inch chamber. It comes with two barrels — 20 inches and 21 inches — so you can switch depending on application. At 6 lbs and 39.5 inches overall, it's light and short enough to work well for smaller-framed shooters.

Detailed Features 

 
The dual-barrel configuration lets you run the shorter 20-inch barrel when maneuverability matters or swap to the 21-inch for added reach. Adjustable rifle sights give more precise aiming than a standard bead, which is useful for slug work or tight shot placement. Three RemChoke tubes (Full, Modified, Improved Cylinder) are included for adjusting shot patterns. The synthetic stock handles weather without warping, and the crossbolt safety is straightforward to operate. 
 

Usage Scenarios 

 
The 870 Compact works well for small game hunting, clay shooting, and as a starter shotgun for youth or new shooters moving to pump-action. The lighter 20 gauge recoil makes extended practice sessions more comfortable than a 12 gauge of similar weight.

The Remington 870 Fieldmaster Compact in 20 gauge gets consistently positive reviews, with a few practical caveats.

Reliability is the main selling point in owner discussions — the 870 platform has a long track record, and this compact version inherits that reputation. The smooth pump action and straightforward operation come up regularly as reasons people recommend it for new shooters. The compact dimensions and 6-lb weight are mentioned as genuine advantages for smaller-framed users and youth shooters, and the lighter 20 gauge recoil gets favorable comments for making the gun easier to shoot over long sessions.

The critical points are more moderate than negative. Recoil with certain 20 gauge loads still surprises some newer shooters, depending on ammunition choice. Factory customization options are limited — the gun works well as-is, but those looking for aftermarket accessories find it less adaptable than some competitors. Both points come up in discussion threads but don't substantially change the overall positive tone.
