Breakthrough Clean BTBGU Universal Bore Guide 17-416 Cal 12.5" Aluminum

The Breakthrough Clean BTBGU Universal Bore Guide eliminates rod contact with barrel rifling during cleaning, preventing damage that degrades accuracy over time. This precision-machined aluminum guide accommodates calibers from .17 through .416, making it compatible with virtually every rifle in most collections.

What Makes This Different

Unlike plastic bore guides that flex under pressure or break after repeated use, the BTBGU features CNC-machined 6061-T6 aluminum construction that maintains perfect alignment through thousands of cleaning cycles. The 12.5-inch length provides superior rod stability compared to shorter guides, reducing wobble that can cause cleaning rod contact with the barrel crown. Internal dimensions are precisely controlled to maintain consistent clearances across the entire caliber range.

Key Features

• Universal compatibility spans .17 caliber through .416 caliber rifles
