This will securely carry just about any two rifle magazines including those USGI, HK, PMAG, ARC, FAL, AK 30/40, LR20 and M14. This pouch has been constructed with Cordura fabric on the front and back, injection-molded polymer sides and a thin sheet of HDPE (high-density polyethylene) to lock the magazines into place. It's all bound with shock cord lacing, creating a flexible yet snug fit for your magazines.
