I have a Pentax 6.5-20x50 with Ballistic Plex. I still have the box and paperwork. It is a great scope and has performed flawlessly on my rifle. However the 50mm objective is a bit more than I need or want. I am looking to see if I can get a trade on a Nikon 4-16 x 40 sf with bdc rectile. I would be interested in either the Buckmaster or Monarch and would take either in trade with cash to offset the difference. Both parties would pay shipping so that niether has to incur a loss as it were. I have excellent refernces on AR15.com and Ebay and Gunbroker I would be open to other scopes like Falcon or something else maybee but how we trade would depend on what you have and how you want to trade. Thanks and Godbless.
