POTD: AK Quad Stack Magazine Posted September 9, 2016 in AK-47 / AK-74 / Everything AK, Photo Of The Day, Shooting Accessories with 37 CommentsTags: high capacity, magazine, quad stack This is a rather rare AK74 magazine that is a quad stack. Similar in concept to the SureFire 60rd quad stack magazines. I am told it holds 60 rounds of 5.45x39mm. Advertisement
