Vortex StrikeFire II 1x Red Dot - 4 MOA Dot - When situations demand split-second target acquisition and maximum field of view, mount up the Strikefire II and get shooting. Compared to its smaller red dot cousins like the SPARC AR or Crossfire, the Strikefire II's larger objective and 30mm tube design provide a larger field of view, and allow it to be mounted at just about any height using most common 30mm rings. A 4 MOA dot is easy to acquire quickly, and is available in red only or user-selected red/green. From AR-15s to shotguns, the Strikefire II offers big time versatility at a price that won't break the bank.
