The Brownells cylinder polishing system is an advanced tool engineered to refine and polish rough or scored revolver chambers, thereby improving extraction efficiency and overall firearm performance. By removing imperfections within the cylinder, this system creates a frictionless surface, significantly reducing the potential for extraction issues during operation.

• This advanced polishing system employs fine grit silicon carbide abrasives integrated into twisted steel shafts, ensuring efficient material removal and delivering a superior polished finish
• The honing tools measure precisely 3 inches in length, ensuring optimal performance and compatibility with industry-standard specifications
• The system facilitates the elimination of machining marks on semi-automatic pistol spring channels, optimizing hammer descent and enhancing cycling efficiency
• To ensure optimal performance and longevity of the hones, it is recommended to use them with Flex-Hone oil
