WTT WTT SWFA 10x42 for 6x42 or Sightron S-Tac

[westsloper]

I have an older SWFA side-focus 10x42 with a mil-dot reticle and MOA adjustments. I'd like to trade it for a 6x or a Sightron S-Tac. I can throw money into the trade. The scope is in perfect operating condition but is used and has ring marks.
