Prosmith Brass Core Nylon Brush - .243/.284/7mm

The Prosmith Brass Core Nylon Brush – .243/.284/7mm is a precision cleaning tool engineered for rifle operators, armorers, and precision shooters who demand barrel integrity without compromise. Available for sale for those maintaining centerfire rifles in these popular calibers, this brush serves as a critical component in post-range maintenance and long-term firearm preservation. Whether you're conducting duty-related weapons maintenance or caring for a precision hunting rifle, a quality bore brush directly impacts accuracy and barrel longevity.

The Prosmith Brass Core Nylon Brush features a tightly wound precision brass core surrounded by soft nylon bristles—a design that effectively removes copper fouling, powder residue, and carbon deposits without scoring or damaging the bore. The brass core provides structural rigidity for thorough scrubbing action, while the nylon bristles protect rifling and throat erosion that harder bronze or steel brushes can cause over repeated cleaning cycles. With industry-standard 8-32 male threading, this brush threads directly onto standard Tetra Gun Care cleaning rods, making installation straightforward for field or bench cleaning.

This brush is ideal for shooters maintaining .243 Winchester, .284 Winchester, or 7mm Remington Magnum rifles—calibers commonly used in precision rifle competition, law enforcement designated marksman roles, and long-range hunting applications. The nylon design is particularly valuable for newer or match-grade barrels where metallurgical protection matters most. Compatible with all standard rod systems using 8-32 threading, the Prosmith Brass Core Nylon Brush specifications deliver reliable performance across thousands of cleaning cycles.
