Brownells
A proper gunsmith brush is one of those tools that separates the meticulous from the rushed. The Brownells Gunsmith Heavy Duty Brush in stainless steel wire—sold here as a 6-pack—gives you the kind of brush reliability you need when you're deep in a detail strip or tackling stubborn fouling in tight corners. Built to aircraft-industry standards, these brushes are engineered to handle the kind of repeated scrubbing that separates casual cleaning from real gunsmithing work.
What makes these stand out is construction that refuses to quit. The handle is 7-ply laminate that won't split, even under aggressive solvent exposure and hard scrubbing. Stainless steel stitching runs the full length of the handle, locking the bristles in place so you won't lose wire mid-job—a detail that matters when you're working on a customer's rifle or your own prized build. The bristles themselves are crimped stainless steel that holds its shape session after session, resisting the collapse that happens with cheaper alternatives.
The geometry is purpose-built for gunsmithing: narrow enough to reach into tight spaces around bolt knobs, receiver corners, and detail work, but with enough bristle density to actually scrub away fouling, carbon, and scale. Whether you're doing regular maintenance, cleaning parts after welding, or prepping surfaces before bluing or cerakote, these brushes deliver the access and aggression you need without the frustration of bristles shedding or handles deteriorating.
At six brushes per pack, you've got backups for the shop and can designate specific brushes for different solvents or tasks without constantly recleaning. This is the kind of reliability gunmakers have trusted for decades.
| Bristle Material | Stainless Steel, Crimped |
| Bristle Diameter | .005" (.127mm) |
| Bristle Length | 1-3/8" (3.5cm) |
| Bristle Rows | 3 rows |
| Bristles Per Row | 7/16" (11.1mm) long |
| Brush Width | 3/8" (9.6mm) |
| Overall Length | 7.76" (19.7cm) |
| Handle Material | 7-Ply Laminate |
| Quantity | 6 Brushes |
Stainless steel wire is aggressive enough to remove carbon buildup, welding scale, and stubborn fouling without damaging the underlying steel or finish. Crimped stainless wire, like these brushes use, holds its shape through repeated scrubbing and resists the collapsing that happens with softer materials, so you're not constantly replacing worn-out brushes.
Yes. The 7-ply laminated handle is designed to resist all common gun solvents and won't split or deteriorate under heavy exposure. The stainless steel construction throughout means no rust or corrosion from wet cleaning.
Yes. The 3/8" width and narrow profile make them ideal for reaching into tight spaces that standard bore brushes and larger cleaning tools can't access. They're built specifically for precision gunsmithing and detail cleaning work.
Six brushes give you backups for the shop and let you designate specific brushes for different tasks or solvents—one for general cleaning, one for aggressive carbon removal, one for final detail work—without having to clean and dry a single brush between jobs. That's how professional gunsmiths stay efficient.
