Designed to easily connect to the lens of your Vortex Crossfire or another sight equipped with a 22mm aperture. Its main purpose is to diminish the noticeable glare from the lens that might otherwise reveal your position. Furthermore, it provides a layer of defence for your lens, safeguarding it in case of any unforeseen mishaps. Even if your optic is backed by a lifetime warranty, this tool guarantees that your gaming day stays unaffected while you await a replacement.
