Breakthrough Clean Bore Guide Features The Breakthrough Clean Bore Guide provides the optimal angle and alignment for effortless patch pushing while shielding the chamber and bore from potential damage caused by a cleaning rod scraping against the feed ramps or chamber walls. Its integrated Pivot Lock securely locks the guide into the upper receiver holding the rifle open at a consistent angle so cleaning can proceed without the action shifting or closing mid-stroke. This locked stable position gives convenient repeatable access to the barrel and chamber every time the rifle is cleaned. The two-piece green and black set is purpose-built for the AR-15 platform. An easy application slot in the guide s design effectively minimizes solvent leakage into the action during cleaning helping preserve the function of internal components like the trigger group and bolt carrier group. By directing solvent and cleaning patches precisely where they need to go the bore guide reduces mess and cleanup time compared to cleaning without one. This makes it especially useful for shooters who clean frequently or who want a more controlled professional-grade cleaning process. The Breakthrough Clean Bore Guide is a smart addition to any AR-15 cleaning kit.
