Good comparison video from Richard Utting on YouTube the other day. He's an exceptionally knowledgeable British long range shooting and scope guru. Like a very well-mannered counterpart to tiborasaurus Rex 
Interesting to hear the thoughts of someone who normally only uses and reviews stuff like Zeiss, Swarovski, IOR and S&B etc opinion on hawke, MTC (ouch) and optisan.

He has some other excellent videos too. Not action packed but super thorough and informative. His review of the Delta Stryker and thoughts on the Athlon Cronus are in the '2017 scope roundup' video too.
