The SINCLAIR INTERNATIONAL 30 CALIBER O-RING ROD GUIDE is designed to seal the barrel off from the receiver, preventing solvent leakage and protecting the trigger assembly.
It is compatible with a wide range of actions and cartridges, specifically fitting Kimber 84M & 84L, and has a .675" bolt diameter for 30-06 Springfield and 308 Winchester cartridges.
The rod guide features an integral solvent port, with an option for a custom version without the port available upon request at no extra charge.
