I bought this from Kalinka optics in 2006 mounted it and never zeroed it. It was on my sam7 for display for many, many years. Still works comes with all accessories  as new.  It has one small blemish on the side under the power lever. Only other wear is the bearing surface  of the locking leaver. I put it on and off alot.    300 dollars cash or money order or trade for an m3000 stoeger semi auto shotgun. Or trade for gen 4 or gen 5 g17 in nice condition.  Offer me other nice knives what do you have to offer? Or trade for a Tops M4X PUNISHER  plus cash . Ftf  or ship  if no local interest.  The lense are perfect just dusty.  Willing to trade for a blackpowder pistol depending on what you have and hopfully  accesseries.
