I am selling my Burris fullfield II tact 30 1x4x24mm. This scope is designed to be used with an AR-15 or a 223. It has a reticle that gives the hold from 100 to 600 yards with a 62 gr bullet. Mounted on the top of the included REPR scope mount is a burris fast fire reflex sight. this setup has only been to the range once I purchased from midway usa a month ago I have tested the reticle out to 600 and the hold's are accurate. I paid 500.00 for the set up will let go for 400.00 or if you have a scope you might be interested in trading let me know.
