P.H. BORE GUIDE 22BR/243/ 22-250/2506/257...SAKO 75

Machined from solid Delrin. 100% solvent resistant. Designed to align the cleaning rod with the center of the rifles bore insuring that no damage can be done by a jag or brush. Guides feature a silicone "O" ring seal that seals off the chamber and insures that no solvent can run back into the action or trigger. For best results, use with optional Solvent Ports, sold separately.
