At the 2014 SHOT Show, The Mako Group/FAB Defense was showing a pair of new magazine coupling devices called the Pentagon Magazine Coupler and the Opposite Magazine Coupler. The concept driving these products is to give shooters faster reloads when they are limited to low capacity magazines.
These new magazine couplers are now shipping, though the wait time is listed as “2 to 4 weeks” on the company’s website.
The Pentagon Magazine Coupler (PMC) is in the shape of a five pointed star. It is designed so a shooter can attach up to five 10-round FAB Defense Ultimag AR-15 magazines. With five fully-loaded mags, the shooter has access to 50-rounds of ammunition.
While the PMC does seem to allow the shooter fast access to more ammunition, I wonder how much faster (if any) this would be than a single magazine change. These units sell for $115.50 and include the five Ultimag magazines. They can be had in either black, OD green or flat dark earth colors. The coupler alone (bring your own Ultimag magazines) runs $22.10.
The Opposite Magazine Coupler (OMC) connects two 10-round Ultimag magazines end-to-end. In theory, this would give the shooter access to 20 rounds by removing, inverting and re-inserting the unit.
The OMC is also available in black, OD green and flat dark earth. With two Ultimag magazines, the OMC is selling for $54.50. Without magazines, the OMC sells for only $15.30. However, the OMC will only work with the FAB Defense Ultimag magazines.
