SINCLAIR INTERNATIONAL manufactures a variety of rod guides for popular target/varmint rimfire rifles, including those for Ruger 77/22, Suhl 150, C, D models.
These rimfire rod guides are designed to allow breech cleaning, accommodating the complex space around ejectors and trigger parts.
The rod guides are compatible with Sinclair Solvent Ports, with the exception of the Anschutz Model 54 guide, and they do not come with an integral solvent port.
