SINCLAIR INTERNATIONAL offers a variety of rod guides for target/varmint rimfire rifles, including the 17 HMR/HM2 for Cooper Model 57.
Rimfire rod guides are designed without O-rings to accommodate the specific dimensions and complexities of breech cleaning around ejectors and trigger parts.
The SINCLAIR rimfire rod guides are compatible with Sinclair Solvent Ports, with the exception of the Anschutz Model 54 guide, and do not come with an integral solvent port.
