They will not work well at all in that 10.
I ran them for a short time in a 22creed 9 twist they did well for about 100 rounds and then never could get them to go again. Will try again with an 8 twist. Have heard similar issues
From what I was told by mack bro's the evo2 and the element are same bases which from what I have been seeing
I was told they were same base screw spacing as defiance, but will have to verify against my anti when my ffl gets back from vaca.
Just ordered one of these today and was shipped today. Will be interesting to play with and compare to my anti.
@jzerfoss what stock is that in the main post?
