The SINCLAIR RIMFIRE GUIDES are designed for cleaning popular target/varmint rimfire rifles, including the Anschutz Model 54 for 17 HMR/HM2 cartridges.
These rod guides are specifically made to accommodate cleaning from the breech side, considering the complexity caused by ejectors and trigger parts.
Although compatible with Sinclair Solvent Ports, the Anschutz Model 54 guide does not include an integral solvent port.
