BoreTech Kartáč nylonový .41 / .416 (3 ks)

Bore Tech BTNR-41-003 is a set of nylon cleaning brushes for rifle calibers .41, .416, and 10 mm, designed for effective yet gentle barrel bore maintenance. The brushes belong to the Proof-Positive line, engineered to deliver maximum cleaning performance without the risk of bore damage or interference with chemical cleaning agents.

Unlike bronze brushes, which can contain a high proportion of copper and react with cleaning agents, these nylon brushes are chemically inert – they do not affect copper fouling indications and are suitable for use with aggressive copper-removal cleaners.

The brush construction features a double-wound brass-free core and firm, high-density nylon bristles, ensuring long service life and consistent cleaning performance. The standard 8-32 thread ensures compatibility with common cleaning rods and accessories.

Key features:

• Caliber: .41 / .416 / 10 mm
• Type: nylon cleaning brush (rifle brush)
• Pack: 3 pcs
• Thread: 8-32 (standard attachment)
• Gentle on the barrel bore – no risk of scratching
• Chemically inert – does not interfere with copper cleaners
• Double-wound core for increased durability
• Suitable for both regular and intensive firearm maintenance

This set is a typical precision cleaning consumable – simple, durable, and designed to perform consistently even when used with modern aggressive cleaning chemicals, where bronze brushes often do more harm than good (especially with false copper indications).
