Honestly, what you pay for a mcmillan I'm not impressed. They are nice stocks, don't get me wrong, but they all seem very clunky. I have owned and used the A5, HTGA, and HTG. I still have the HTGA. I think my downfall was when I got my first manners stock. It's fit and feel is so much better. If mcmillans were priced around the grayboe area, I would say they win all day, but if you're paying that much go manners.
If you want to save money and still have a quality stock the BC M40 and the new long range target model with the adjustable cheek piece is the way to go! I have used BC. I really like them.
