The Brownells Double-Up Mops in cotton give you a practical two-in-one cleaning tool for 37/40mm bore work. Whether you're maintaining specialty firearms, launcher tubes, or tear gas dispensers, this 3-pack approach means you'll have spares on hand and can keep your workflow moving without constantly swapping out worn components. Cotton construction absorbs and holds cleaning solvents effectively, making it ideal for wet-stage bore scrubbing.
What sets the Double-Up design apart is the modular coupler system. Both the mop and the included brushes feature durable aluminum couplers—male and female—that let you thread them together in any order you choose. That flexibility means you can pair the cotton mop with a bronze brush, a nylon brush, or stack them in sequence to suit the specific condition of your bore or the stage of your cleaning cycle. No more rummaging through a toolbox for the "right" combination; you build it as you need it.
Three packs give you enough components to set up multiple configurations and keep backups ready, especially useful if you run these tools regularly or maintain more than one firearm. The aluminum couplers are built to last through repeated connections and disconnections, so they won't wear out or strip easily with normal use.
| Bore Diameter | 37/40mm |
| Mop Material | Cotton |
| Coupler Type | Aluminum (male and female) |
| Quantity | 3-pack |
The 3-pack includes both bronze and nylon brushes alongside the cotton mop, all compatible with the same aluminum coupler system so you can combine them as needed.
The Double-Up Mops feature aluminum couplers (male and female) that attach to each other. Compatibility with other cleaning systems depends on those systems' coupler design. Check your rod or jag interface before purchase.
The cotton mop is designed to absorb and hold cleaning solvents, making it best suited for wet-stage bore cleaning and scrubbing.
The aluminum male-and-female couplers let you stack the mop and brushes in any order without needing different tools or adapters, so you can customize your cleaning sequence on the fly—brush first, mop second, or any configuration that matches your cleaning plan.
