The Burris Fullfield TAC30 Rifle Scope is designed to stand up to the hard use of tactical shooters. This scope features high quality lenses with HiLume multi-coatings to provide a clear picture. Double-spring tension and an oversized ball-joint secure the hand-fitted internal zoom-assembly. The main tube is constructed of aircraft grade 6061T6 aluminum. Each scope is purged with laboratory-grade nitrogen to eliminate internal moisture and sealed with Burris-exclusive quad seals. The adjustment system is positive and repeatable with audible clicks ensuring unfailing shot-to-shot accuracy in all environments. Another key feature is the Ballistic CQ reticle which allows for rapid engagement of close quarters targets while also providing holdover points out to 600 yards when shooting a 62 grain 5.56x45mm load. Included with the scope are a Fastfire III Red Dot Sight and an AR-P.E.P.R. Mount. The Burris Fullfield TAC30 Rifle Scope is covered by the Burris Forever Warranty. Note: The illumination button was designed so that it will not turn on when accidentally bumped. You must push the button with what you may perceive as excessive force to turn the illumination on/off or to switch between different levels.
