text: Just something to think about. Seems red dot sights are the most popular sight to use. This is good however they require batteries to function. If war or large scale conflict was to break out batteries will be nearly impossible to find. You may want to think of an alternative sight platform. There are sights that can be lighted up in red or green but have a black reticle when turned off or batteries die. These are Prismatic sights with an etched reticle so they will be working when others die out. Another option are Mepro Lite sights they require no batteries period and work day and night. They are also completely submersible with a lift time guarantee. Just throwing some thing to think about. If conflict does start it won't last days ,weeks bur for years yes years plural.
