The PTM Edge KNB-17 Replacement Knob for UCX-17 PRO Mirror in silver is a precision-engineered component designed for operators who depend on reliable optical adjustments in the field. Machined from billet aluminum and anodized for corrosion resistance, this replacement knob delivers years of maintenance-free operation across diverse environmental conditions—from arid ranges to humid coastal climates where standard finishes fail.
Construction from billet aluminum ensures both durability and lightweight performance without sacrificing structural integrity. The anodized finish provides a hard, non-reflective surface that resists corrosion, salt spray, and abrasion from repeated handling and gear contact. At just 0.25 lbs with compact dimensions (2 x 1 x 2 inches), the KNB-17 adds negligible weight while maintaining the ergonomic profile users expect from PTM Edge optics. The silver finish offers visibility during daylight adjustments and maintains low-light discretion when required.
This replacement knob addresses a critical wear point in extended-use optics. Whether mounted on training rifles, duty weapons, or emergency preparedness setups, adjustment knobs experience repeated torque and environmental exposure that eventually degrades original components. Having a verified replacement on hand ensures zero downtime during equipment maintenance or field repairs. The KNB-17 is sold as an individual unit, making it ideal for spare parts inventory or immediate repair needs without purchasing duplicate optics.
Compatibility is limited to the UCX-17 PRO Mirror system, so verification of your optic model before purchase is essential. This precision component maintains the same tolerances and fit as original PTM Edge equipment, ensuring seamless integration and reliable adjustment mechanics. For serious shooters and preparedness-minded users who rely on consistent optical performance, the KNB-17 represents preventive maintenance and operational continuity in a single, affordable replacement part.
