Hate to say this but the King in ST chasis is a lot nicer than the Benckmark in that stupid ugly stock, I know the stock on the Bechmark is for 100 yard bench rest. If I were to do it over I would purchase the Benchmark , scap the Benchmark stock, put the Mk 2 .30 action in a ST chasis , with long bottom rail 700 cc bottle . . Then I would I have a LIGIT 100 yard bench rifle & a hunting rifle , that would be duel purpose. Your wording is offf. I was referring when I owned the King, I took it out of the GRS stock, & put it in the ST chasis. FX calls it the King because it action was in a GRS stock, did you forget that ? Essentially the MK 2 Dynamic block is the upgraded action version with improved trigger. I was referring to my MK 1 King to compare it to the UGLY Benchmark. I rather have in my opinion a DUEL purpose rifle, not have a 100 yard bench rifle . Don't forget FX is great @ marketing, that's why the came out with the Benchmark, so people say OOH I have to get this! .
