Accuracy in the Mk12? A brand new Mk12 Mod0 upper from PRI.

Watch latest videos, sometimes even early releases! Sign up for the newsletter : How tight does a brand new Mk12 group? This is a PRI factory assembled Mk12 Mod0 upper that we purchase for the express reason to revisit the never-dying question: How accurate is it? Since our first coverage of the Mk12 Mod0 in 2018, there have been people asking why our groups seem to be larger than what some other show on the internet. We invited people to submit their own 9-shot groups instead of just 5-shot groups (or worse, 3-shot groups) to represent the Mk12’s accuracy.
