The Leapers UTG 4.2" ITA Red/Green Dot Scope allows fast, reflexive aiming in multiple lighting situations. The ITA (Instant Target Acquisition) 1x scope excels in close quarters combat as the red or green illuminated dot helps shooters adapt to virtually any environmental background. The dot illumination rheostat dial provides quick yet fine brightness adjustment. This ITA scope includes a high-profile cantilever mount and low-profile vertical mount that are compatible with any Picatinny rail. Both mounts can co-witness with standard AR-15 iron sights and both feature a quick-detach lever lock that makes it easy to install or remove.
