Features 

The 26-inch vent rib barrel balances handling and sight radius well for field and sporting clays use. Twin action bars prevent the binding and twisting common in single-bar designs, giving a smooth pump stroke. The solid steel milled receiver is the foundation the 870 has always been known for. Three flush Rem chokes are included -- Improved Cylinder, Modified, and Full -- covering most field and clay shooting scenarios. The Fieldmaster finish adds corrosion resistance without changing the walnut stock's traditional look. 
 

Who It's For 

The 870 Fieldmaster in 20 gauge suits hunters targeting upland birds and small game, sporting clays shooters, and anyone who wants a lighter-recoiling shotgun platform. At 6.3 lbs it's manageable for smaller-framed or younger shooters. The 870 action has decades of documented reliability and is straightforward to maintain.

The Remington 870 Fieldmaster 20GA with 26-inch barrel earns consistently positive feedback, anchored by the platform's long-standing reputation for reliability.

Owners frequently cite the solid construction and durability as primary strengths -- the 870 has been trusted in the field for decades, and this 20-gauge variant carries that reputation. The 20-gauge chambering is specifically praised for manageable recoil, making it accessible for a wide range of shooters including those who find 12-gauge punishing.

The 26-inch barrel draws positive comments for the balance it provides between handling in the field and sight radius for clay work. Ease of cleaning and maintenance is a recurring theme -- 870 owners consistently note how straightforward the action is to service.

Critiques tend to focus on personal preference rather than defects: some shooters prefer 12-gauge for more versatility, and a few buyers note the 870 Fieldmaster is heavier than some newer synthetic-stocked competitors. Customization requests come up occasionally -- the 870 platform has extensive aftermarket support, which most owners appreciate. Overall sentiment is strongly positive for buyers who want a proven, traditional pump-action field gun.
