Description
Description
Stay confident in your zero. Designed to help track optic screw movement over time, this fine-tip oil-based paint marker lets you apply precise witness marks to your red dot and mounting screws. If those marks shift, you'll know your optic may no longer be secure—or zeroed.
✅ Perfect for red dot installations – Mark your screws after torquing to spec
✅ Oil-based, permanent ink – Resists cleaning solvents, water, and recoil-induced wear
✅ Multi-surface compatible – Works on metal, polymer, Cerakote, anodizing, and more
✅ Quick-dry and fade-resistant – Reliable for long-term optic setups
✅ Available in Red, White, or Blue – Choose high-contrast for your slide/optic color
Trusted by gunsmiths and DIYers alike, this marker adds a layer of visual confirmation to every optic install.
