The Beez Combat Systems (BCS) AK47 Chest Rig has now been around for about a year. In that time, it has seen use in Africa, Iraq, Afghanistan, and other countries around the world.
There are a few key features that seem to be the reason for the popularity of this rig. First, it is very low profile – low profile enough to wear over a plate carrier without excess bulk. Second, the buyer can choose whether they would like a 3, 4, 5, 6, or even 7 magazine configuration. Third, the pull forward design of the harness makes adjusting the rig easy, even while you are wearing it.
BCS continues to listen to end user feedback to refine this design. Check their post about 1 year with the AK47 Chest Rig on the BCS Blog.
