FAB Defense PMC

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.

FAB Defense OMC

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.

    I feel like if you hold a fully loaded pentagon mag over your head and chant the magic words a bolt of lightning would come down and your AR would magically appear.

    Not a bad idea for working around certain state restrictions on magazine capacity where they apply, but not that great either. However, even in such cases I think it is a lot better to use single magazines and practice hard at quick, efficient magazine change-outs --- not only because reloads can be just as fast, but, more importantly, you will be able to maintain a slim, short profile for your rifle with all the handling advantages this implies, not to mention less bulk and weight ( especially in the case of the pentagonal magazine adaptor ). I can see that the OMC adaptor is a lot better in this respect but, as others have pointed out, a side-by-side configuration would have been more compact and efficient while preventing the ingestion of debris into the bottom magazine.
