By customer request we developed these for coupling two 308 PMAGs together for having up to fifty rounds available without using a drum.

Uses a 4mm Allen wrench and an 8mm socket to install (not included).

PMAGs are not included.

NOTE: Does not work with 40 round ProMag 308 magazines. Only works with Magpul brand PMAG 308 magazines!
