223 Brass Marker

Taking all the suggestions and personal experience, I have created a better brass marker for any 223 bolt face round. Utilize the markers (sharpie or other similar) existing cap lock to secure into hole(s) while markingNow will mark case rimSide opening so you no longer need to slide it the full length and can either mark just the bottom or just the side of the brassImproved the rim retention in slotOverall tolerance improvements
