Prosmith Brass Core Nylon Brush - .17 Caliber

The Prosmith Brass Core Nylon Brush - .17 Caliber by Tetra Gun Care is a precision barrel cleaning tool engineered for shooters who demand non-damaging, effective fouling removal. Whether you're a law enforcement officer conducting post-duty maintenance, a competitive rifleman optimizing accuracy, or a military armorer managing multiple platforms, this brush delivers professional-grade cleaning without compromising barrel integrity. The .17 caliber specification makes it essential for owners of specialized varmint and precision rifles that see heavy use and require meticulous bore care.

The brush features a tightly wound brass core wrapped with soft nylon bristles—a proven design that removes powder residue, copper fouling, and lead buildup without scoring or damaging precision-rifled barrels. Unlike steel brushes that can leave microscopic scoring that degrades accuracy over time, nylon construction protects bore walls while maintaining aggressive cleaning action. The industry-standard 8-32 male thread (5-40 for .17 caliber) ensures compatibility with universal cleaning rod systems and sectional rods used across tactical and hunting environments. This threaded connection is the ergonomic standard preferred by professionals who rotate between multiple firearms and expect quick, tool-free attachment.

Field-proven by precision shooters and dedicated to those who maintain rimfire and centerfire .17 caliber platforms, this brush integrates seamlessly into any standardized cleaning kit. Pair it with quality bore solvent and a brass rod to extend barrel life and maintain the sub-MOA accuracy expected from modern .17 rifles. Regular use after each shooting session prevents copper fouling buildup that can shift zero and degrade ballistic consistency—a critical consideration for long-range and competition shooters.
