Damn! thanks for the info!
What's your expectation for accuracy in a semi like either of these platforms?
I have been more than satisfied with the accuracy of my MK7. I have a new trigger coming which will hopefully improve it even further. My bolt guns make me happy with their tiny groups, but I didn't have the same expectations for a semi. Seeing Jerry post up some nice tiny groups definitely motivates me to build another upper with a match barrel in a different caliber to see how small the groups will go.
I think either gun will perform in stock form. Just depends on how long you'll be satisfied with it in stock form
