Solving Shotgun Extractor Problems with Flex-Hone® for Firearms Tools

Posted by Team BRM on Jan 2, 2018 9:54:32 AM

Remington 870.jpgMembers of the Guns group on Reddit exchange information about firearms tools and performance. In a thread called This is the worst gun in my collection, several users cited the Remington Model 870 for shotgun extractor problems.

 “It doesn’t feed right at all,” said one shooter. “The shell gets stuck in the chamber after it’s been fired,” replied another. The M870 is the world’s best-selling shotgun, so these reports might surprise some gun owners. As Flex-Hone® for Firearms users know, however, the solution starts with the surface finish.

Surface Finishing for Shotgun Chambers

If the chamber’s surface finish isn’t smooth enough, brass from fired shells may accumulate in recessed areas. Residual tool marks aren’t the only problem either. If the surface finish contains nicks and scratches, plastic adhesion can occur. Brass scarring can cause sticking and failures to eject (FTEs), too.  

To address shotgun extractor problems, some gun owners result to brute force. Yet slamming the gun on the ground risks damaging the shotgun extractor. As a member of the Guns group on Reddit explained, the best approach is to “fix the root problem” and “get that chamber smooth”. This approach, the shooter added, involves BRM’s Flex-Hone® for Firearms tool. “I purchased a Flex-Hone to get mine done,” the shotgun owner explained. “Now I can shoot the cheap low brass without issue at all.” 

Flex-Hone® for Firearms Tools

madeintheusa_seal_150px.pngMade in the USA by Brush Research Manufacturing (BRM), the Flex-Hone® for Firearms surface finishes the walls of firearms cylinders. BRM’s gun tools aren’t meant to replace gun cleaning brushes, but are designed for periodic gun maintenance. For shotguns, BRM supplies barrel hones, chamber hones, and forcing cone hones that gently smooth metal surfaces. The resulting finish is more uniform, and resists corrosion and wear while reducing fouling.

Flex-Hone® Firearms tools mount in handheld electric drills and, as this How-to Video explains, run at low RPMs. User should choose a high-quality lubricant such as Flex-Hone® oil and avoid overhoning the cylinder walls. Unlike rigid hones, Flex-Hone® tools aren’t built for heavy-duty material removal. By keeping the bores of your firearms at the precise dimensions required, Flex-Hone® for Firearms tools support proper gun maintenance and performance.
