This riflescope is optically brilliant and is mechanically unmatched.  The original ATACR was praised “a revelation”.  This scope grants that revolutionary riflescope with first focal plane, giving it an entirely new dimension.  Equipped with ED glass, it enables target engagements at distance previously considered to be “out of range”.
