Caliper,

speaking from experience, The Axis isn't the best platform to build from... You have more aftermarket options for the 10, 11, 12, 16... However, everyone has their preferences. The Axis has a very high bolt throw and I had issues with the bolt rubbing on my ocular lens housing. It's created a cosmetic issue, but nothing as far as function. The Trigger on the "original axis" is really heavy and not the best trigger. The Accutrigger is much better in my opinion.
