Allen Company BT-270/284/7NBB Bore Brush .270 .284 7mm

Product Description

The ALLEN COMPANY BT-270/284/7NBB is a nylon bristle bore brush designed for cleaning rifle barrels chambered in .270, .284, and 7mm calibers. The brush features a brass core that resists corrosion and holds the bristle configuration during repeated use. Nylon bristles provide effective scrubbing action for removing fouling, carbon buildup, and residue without the risk of scratching or damaging the bore's rifling. This brush is a standard tool used by gunsmiths, armory technicians, and experienced firearm owners during routine barrel maintenance and cleaning procedures.

This bore brush is suited for routine field and bench cleaning of bolt-action, semi-automatic, and lever-action rifles chambered in .270 Winchester, .284 Winchester, or 7mm variants. It fits standard cleaning rod thread patterns and works with most solvent and patch cleaning systems. The nylon construction makes it compatible with a wide range of bore solvents and cleaning solutions commonly used in professional and hobbyist firearm maintenance.

Installation Notes

Always ensure the firearm is unloaded and the action is open before beginning any cleaning procedure. Thread the bore brush securely onto a compatible cleaning rod before inserting into the barrel. Run the brush through the full length of the bore in smooth, consistent strokes. Do not reverse direction of the brush while it is inside the barrel, as this can stress the bristle attachment and core.
