Pro-Shot Products Stopper Series, Adjustable Bore Guide, Centerfire .22 Caliber - .30 Caliber BG22-30 BG2230

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.
