Frequently Asked Questions

What are common quality control issues with newer Remington 870 shotguns?

Newer Remington 870 models, especially those made after the Freedom Group acquisition, may have rough machining marks in the chamber. These imperfections can interfere with the extractor, leading to failures during the ejection or extraction cycle of spent casings.

How can extraction issues on a Remington 870 be fixed?

A common DIY fix involves polishing the chamber. This can be done by wrapping steel wool around a dowel rod, inserting it into the chamber, and using a drill on a low setting to smooth out rough machining marks, improving extraction reliability.

What are the key differences between the Remington 870 Police Magnum and Express models?

The Police Magnum typically features a more durable Parkerized finish (vs. painted), a metal trigger guard (vs. polymer), a forged extractor (vs. MIM), and a stronger carrier dog spring, indicating a higher level of build quality and reliability.

Why might someone prefer a Remington 870 over a Mossberg 500/590?

The primary deciding factor often comes down to the safety mechanism. Remington 870s have a trigger-guard mounted safety, while Mossberg 500 and 590 series shotguns feature a tang-mounted safety. User preference dictates which is more intuitive.
