When purchasing Sinclair International or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

The Sinclair Two-Piece bore guide system has been designed to assist shooters with the best possible alignment of their cleaning rod to the bore. This system uses a guide within a guide. The guide body will go into the action and seal the chamber using an O-ring, similar to traditional bore guides. Additionally, a separate guide will slide into the rear of the guide body to offer a slip fit for the cleaning rod. The 8" insert is a tight fit, which prevents the rod from flexing and keeps it centered, so there's no contact with the rifling while cleaning. You can select the guide body to fit the cartridge that your rifle is chambered for, and then choose the insert with the inside diameter that fits your rod. Both guide body and insert are machined from Delrin and come with rubber O-ring seals to prevent solvent from entering the action. Note that bore guide bodies are designed to fit the Remington 700 and other rifles equipped with .700" diameter bolts.

Please note that inserts are sold separately.
