M17 CQC, M17A2, what's the difference?

The M17 CQC has first launched just over 4 years ago, and since then it's seen a collection of revisions to improve performance, reliability, and ease of use. These revisions were made based on valuable feedback from you guys, the people in the mud and dirt using the markers every single weekend. 

With the recent price drop on the M17A2, we've seen more and more questions asking what the difference is between the M17CQC and A2 models, so we made you a little video.
