Bore Tech AR-15 Patch Guide 6mm ARC / 6.5mm Grendel

The Bore Tech AR Patch Guide is a patented, muzzle-end cleaning tool designed specifically for the AR-15 platform, in the 6mm ARC and 6.5mm Grendel chamberings. It inserts through the upper receiver and seats in the chamber via an O-ring seal, precisely aligning the cleaning rod with the bore and preventing the rod from dragging on the locking lugs or chamber edges. The key feature is an industry-exclusive, hands-free patch spiking system: lay a patch over the angled patch plate, apply your solvent, and push the rod forward — the plate spikes the patch cleanly without the mess of hand-spiking. The guide body features precision-moulded and CNC machined components, and a solvent-resistant, interchangeable front adapter sized for the 6mm ARC and 6.5mm Grendel cartridge family. This adapter can be swapped with other Bore Tech AR-compatible adapters for different calibres as needed. At 13.5 inches long, the guide adds to the effective rod length required, so ensure your cleaning rod is long enough for your barrel. Proudly made in the USA.
