For real deal use and even for airsoft, The Firearm Blog takes a look at the Bushnell RXS-100 red dot sight that can be mounted on pistols... "In this episode of TFBTV, Hop tests the new $100 Bushnell RXS-100 on a Taurus G3 TORO to find out if it can compete with pistol red dots costing up to five times as much. The RXS-100 and RXS-250 are two new pistol red dots from Bushnell that use the common Delta Point Pro mounting pattern. The RXS-250 has a surprising amount of features for the price, but the RXS-100 strips away the high-end features in order to be the cheapest pistol red dot on the market. But how cheap is too cheap?"
