Otis 6.5/264cal Brush/mop Combo Pack

The Otis 6.5/264cal Brush/Mop Combo Pack delivers precision bore maintenance for precision rifle platforms chambered in 6.5mm and .264 caliber. This two-piece cleaning system combines a bronze brush and a mop head, both sized specifically for mid-range rifle bores where fouling control directly impacts accuracy and barrel life. Designed for shooters who understand that consistent bore cleanliness is foundational to repeatable long-range performance, this combo pack integrates with standard Otis cleaning rods and is built to military specifications.

The brush-and-mop configuration addresses the two distinct cleaning phases that serious riflemen encounter in the field. The bronze brush scrubs accumulated powder residue, copper fouling, and carbon buildup from the lands and grooves; the mop follows to distribute solvent evenly and absorb loosened debris. Both components are manufactured to precise bore dimensions—oversized enough to ensure positive contact with bore walls, yet engineered not to force unnecessarily during the stroke. This balance protects bore integrity while delivering effective cleaning action across multiple cleaning cycles.

This combo pack serves precision rifle operators, competitive long-range shooters, and hunters who maintain their own firearms. 6.5 Creedmoor, .264 Winchester Magnum, and other cartridges in this bore diameter bracket require disciplined barrel maintenance to preserve the tight tolerances that define their ballistic advantage. Field-stripping and bore maintenance between range sessions or after field use prevents corrosion, reduces string-to-string velocity variation caused by fouling, and extends barrel life in high-round-count shooting disciplines. The Otis system's modular design and compatibility with widely available cleaning rods make this a practical addition to any precision rifle maintenance kit.
