Brand new. I installed it and sighted it in but its never seen the woods.Its 4 pin micro adjust with .019 fibers Its a great sight,virtually bullet proof! I just need money and am going to put the old one back on. . Asking 150$ Retails 199$
JM...I just bought one here last month and I believe the inside diameter is around 1 5/8 and maybe the outside diameter is around 1 7/8. Justin did a review in his blogs on this sight around the first of Aug. and he sent me some more info. and I believe those measurements are what he said. Sept. specials had them here last month for $135.00...that was a GREAT DEAL!!! I love the sight... seems to ber very well constructed and great protection on the fibers...good luck. My next choice was a Spot Hogg.
