RMR-A will come in two reticle choices, 3 or 6 MOA run for a couple of years of ‘normal’ use on a single CR2032 battery. It weighs about 1 ounce bare. It will be priced around $550 and will not include a rail mount/adapter. You’re going to to pony up anywhere from $70-100 more for a co-witness height mount. (The mount on the prototype we photographed is more of a handgun mount since it’s too low to work on an AR or SCAR platform.)
