Protects From Cleaning Rod Damage & Keeps Solvent Out Of Receiver
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.
