The SINCLAIR INTERNATIONAL ANSCHUTZ 1451T RIMFIRE ROD GUIDE is designed specifically for target/varmint rimfire rifles and is part of a large assortment of rod guides.
These rimfire rod guides are complex to make due to the absence of an O-ring and the presence of ejectors and trigger parts, but they facilitate cleaning from the breech.
While the rod guides are compatible with Sinclair Solvent Ports, the Anschutz Model 54 guide is an exception and does not include an integral solvent port.
