Uberti 1866 & 1873 Brass Magazine Cap Screw
Upgrade your compatible lever-action rifle or carbine with the SliX Cap Brass Magazine Screw. Precision CNC-machined as a direct replacement for the factory magazine cap screw, this premium upgrade improves corrosion resistance, simplifies routine maintenance, and helps keep the magazine spring properly centered for smoother, more consistent cartridge feeding.
Unlike factory steel magazine cap screws that can rust, seize, or become difficult to remove over time, the solid-brass SliX Cap provides dependable corrosion resistance while adding a classic appearance that complements Uberti lever-action rifles.
The integrated spring-centering design helps maintain proper magazine spring alignment as cartridges travel through the magazine tube. By keeping the spring centered, cartridges are presented more consistently to the carrier, promoting smoother feeding and more reliable cycling.
