    (2) DuraMag SS 30-rd magazines, 5.56 caliber (FDE/Black Followers)

    Posted by Edward in Sarasota, FL on 27th Jul 2024

    Quality: Solid (i.e., 410-SS, T-360 coating, EverFlex spring, Post n' Hole welding). Design: “Form follows function.” (i.e., LipLock, high visibility AGF). Performance: First magazine, loaded with thirty Hornady TAP Urban .223 Rem 55-gr functioned flawlessly in my M16A1/M203. Did not experience any issues with the second magazine loaded with twenty USGI Lake City M200 blank cartridges in my LMT Defender/M203 carbine. Value: Another great proposition from CPD.
