The X2R is made to handle any rifle magazine but the double decker design lets you have 2 in the only 3" of space on your platform. Like the original it has polymer sides with Cordura front and back and shock cord and a thin sheet of HDPE to lock in just about any magazine. Your magazines are help in place ready for silent deployment with the shock cord to keep them in place as additional security that can be moved when it is about to get exciting. However, if additional retention is desired, webbing tabs are sewn in on the top for use of "over the top" bungee retainers. In addition, loop Velcro is sewn on the interior for the user that utilizes adhesive hook on their magazines.
Fits:
USGI, HK, PMAG, ARC, FAL, AK30/40, LR20 and M14 magazines
