FIREARMS BARRELS, CHAMBERS AND MORE

YOUR FINISHING PROCESS JUST GOT EASIER

Overview

For firearms manufacturers, gunsmiths and hobbyists alike, maintaining the internal surfaces of a firearm is essential to ensure peak performance, safety, and longevity. Firearms cylinders are subject to intense pressure, heat, and fouling with each shot, and their surface condition directly impacts accuracy, reliability, and ease of maintenance.  The FLEX-HONE provides a simple, effective way to clean, polish, and condition critical components—ensuring your weapon operates at its peak. 

The FLEX-HONE® tool is a versatile solution for improving surface finish across various firearm components, including shotgun barrels, cylinders, chambers, slides, and magazine tubes. In shotgun barrels, it removes oxidation, corrosion, scratches, and plastic residue, leaving a smooth bore that resists future buildup and extends barrel life. When used in revolver cylinders and chambers, it enhances loading and ejection by allowing rounds to drop in and out smoothly while reducing brass scarring and making reloading easier and more efficient. Additionally, FLEX-HONING slides and magazine tubes provides a durable, low-friction surface that improves cycling and wear resistance.

Why Surface Finish Matters in Firearms 

Key FLEX-HONE® Benefits

1. Enhanced Accuracy and Consistency Rough or pitted surfaces in chambers or barrels can cause inconsistent bullet seating, reducing shot accuracy. 

2. Improved Fouling Removal Smooth, refined surfaces resist carbon, copper, and lead buildup more effectively, making cleaning easier and reducing the chances of corrosion or malfunction. 

3. Reduced Wear and Tear Proper surface finishing helps minimize friction and abrasion between moving parts—critical in revolver cylinders, semi-auto chambers, and forcing cones—thereby reducing premature wear. 

4. Enhanced Safety A well-maintained chamber and forcing cone ensure proper cartridge seating and sealing, preventing dangerous pressure spikes or misfires. 

5. Improving Without Changing The tool produces this finish with a minimum of stock removal, ensuring that the bores of your firearm remain at the precise dimensions required.
