Brownells Standard Line Brush, Nylon, .50 Caliber Rifle, 12 Pack

Keeping your .50 caliber rifle clean and accurate starts with the right bore brush. The Brownells Standard Line Brush in nylon is purpose-built to work with modern bore cleaners that aggressively tackle copper and bronze fouling without damaging your bore. Unlike brushes that can leave scratches that hurt accuracy, nylon bristles are tough enough to handle aggressive chemical cleaners while remaining safe for precision rifle barrels. This 12-pack gives you plenty of brushes for the range, the field, or the shop—so you'll always have one ready to go.

What sets these Brownells brushes apart is the construction. The shank is one-piece, looped and wound steel (not two pieces twisted and cut), which means better durability and a more reliable fit in your cleaning rod. The design has been proven in the field and the shop for years, and Brownells packed them in bulk to keep the cost down without cutting corners on quality.

Whether you're a competition shooter maintaining a precision rifle, a hunter preparing before the season, or a gunsmith who goes through brushes regularly, a 12-pack of nylon bore brushes makes sense. You'll always have a fresh brush on hand, and you won't hesitate to use one because you've got spares. The nylon bristles won't scratch your bore, and they'll stand up to whatever cleaner you prefer.
