This was originally meant to fulfill the role of a Mayflower Chest Rig by Velocity Systems, which was also the namesake. Now this chest rig can do so much more than what the Mayflower was meant for. Featuring a FAT pocket that can fit up to EIGHT AR-15 rifle magazines, this chest rig can be built out for any hefty mission set. You even get a second pocket up front for up to five pistol size slots or three more rifle magazines. On top of all that there are three rows and columns of MOLLE webbing on each side, allow another plethora of opportunity. Let's face it, micro chest rigs are cool and all, but with ammo coming back in fashion, a big boi like this is what you need. The rig comes with two 4 rifle mag slot inserts and one 5 pistol mag slot insert. I really admire the velocity systems rigs, but they are untouchable for their cost, so the Santa Maria rig offers a reliable budget option.
