Frequently Asked Questions

What are the key modifications for a duty-ready Remington 870 shotgun?

Key modifications include upgrading internal parts for reliability, installing a 14-inch barrel, adding an Aridus Industries CROM mount with a Holosun red dot, a modular side-saddle, Magpul furniture, and a weapon light. An oversized safety is also recommended.

Why is replacing MIM parts important on a Remington 870?

Replacing Metal Injection Molded (MIM) or plastic parts with more robust alternatives is crucial for ensuring the Remington 870's reliability, especially during high-round-count training or demanding operational scenarios where failure is not an option.

What benefits does the Aridus Industries CROM mount offer?

The Aridus Industries CROM (Co-Witness Ready Optic Mount) allows for a true co-witness with iron sights when a red dot optic like the Holosun 503GU is mounted. This ensures you can still use your iron sights if the optic malfunctions.

How does the Magpul SGA stock improve shotgun ergonomics?

The Magpul SGA stock is noted for its superior ergonomics, particularly in providing easier access to the action bar release compared to traditional pistol grip stocks, facilitating smoother manipulation of the shotgun's action.
