A must have - Trijicon Lenspen for Optics for cleaning of Trijicon ACOG Rifle Scopes, Night Sights, Reflex Sights

I expected nothing less from Trijicon. Excellent glass cleaner. I use it on my RMR and scope lenses. Gets the class back to crisp and clear. Is there cheaper options, yeah. But with my experience, I've learned in most cases it is better to buy for quality and trusted name brands over cheap alternatives that need to be replaced several times.
