The RJK Ventures MAG|Coupler is a magazine coupler to join two Magpul M3 AR-15 PMAGs together.
Ideal for ranges or locations with restrictions on magazine capacity, or competitions requiring a magazine change, the coupler simply replaces the PMAG baseplate with dual coupler to connect two magazines back-to-back.
Manufactured from tough glass reinforced polymer to match the PMAGs the couplers offer a snug no wobble fit but can still be removed when required.
Commonly used with a pair of Magpul 10 round AR-15 M3 PMAGs they can also be used with other sizes e.g. 20s, 30s or even 40s. Works with magazine pouches when linking 10 round mags.
