Description
One-piece Delrin® bore guide replaces the bolt/carrier group during cleaning to center the cleaning rod and prevent solvent from leaking into the trigger group or the upper receiver. Snug-fitting O-ring at the front seals off the chamber. Slot at the rear lets you apply solvent directly to patch or brush, while keeping it fully contained in the guide. #BG22-30 -.22 Centerfire-.30 Cal short or long actions
